"It's another small rush hour of traffic, please be safe on the way home from work, it's 12 noon Beijing time. ”

The radio station was punctual in announcing the time. The host then said: "It's hot today, and the temperature is 40 degrees Celsius." Everyone should pay attention to sun protection when going out to avoid heat stroke. ”

The sparrow is wheezing in the tree, its thick feathers and special physiological structure make it difficult for it to lower its temperature, and the only way to hide in the shade of the tree is to sleep in this nearly forty degree space.

At this time, Xu Wu was very extravagant, he held the Coke that had just been taken out of the refrigerator in his left hand, the iced watermelon that had just been cut in his right hand, turned on the air conditioner in the room, and asked Phantom Moon who was standing aside: "Phantom Moon, how do you use gene regulation?" It's been unlocked for so long, and I've always forgotten to use it. ”

"The genetic adjustment system is used by the creatures on the island, and the activation instruction is adjustment. Phantom Moon explained simply.

Xu Wu stopped eating melons, looked at Phantom Moon sluggishly, and asked at an astonishing speed: "Gone?"

Phantom Moon nodded and added, "Please learn by yourself in practice for the follow-up content." ”

"If you talk more, you won't die. Let's talk about some examples!" Xu Wu hopes to get more information, he has suffered too many losses before, and he has a long memory.

"Okay, given your IQ, I can only help you. After Phantom Moon finished speaking, her eyes suddenly lost their highlights, and her whole person flickered.

After a while, Phantom Moon became normal, her eyes regained her brilliance, and she said, "Search for the blank game data, and now use the information collected from the Internet as an explanation."

The earliest gene editing technology in recorded history was gene recombination, in which homologous fragments (similar fragments) were injected directly into cells, so that gene fragments were exchanged to achieve the purpose of adjusting genes.

With the gradual development, there are also methods to guide nucleases to cut gene fragments by recognizing specific sequences...... (Proteases that cut nucleic acids, i.e., hydrolases of DNA or RNA)"

Xu Wu interrupted Phantom Yue's explanation with black lines on his head: "Don't say something I know." Why is the island's database blank?,It's so black technology.,But it's like a three-no game.,There's no explanation.。 (Interested parties can check the specific content of gene editing, but the authors are afraid that their vocabulary and understanding will mislead others.) ）

"I don't know why, the game data can't be read, it feels like it's been destroyed. Phantom Moon frowned and said with some confusion.

For the domineering of this game, Xu Wu is used to it, and he has no desire to resist directly, he only hopes to quickly test whether the genetic adjustment of the island can achieve his goal.

The projection of the island was turned on, and he quickly rummaged through the grassland.

Although rabbits were initially stocked near lakes, as the island's ecosystem continued to build up and the variety of food became abundant, hares continued to migrate to various parts of the island, most commonly in grasslands.

Xu Wu quickly turned out a nest of rabbits in an inconspicuous cave and selected one of the rabbits that had just been born. According to the instructions taught by Phantom Moon, he spoke: "Target, rabbit in vision, adjust." ”

The entire island entered a state of time stop with Xu Wu's command, all the creatures in Xu Wu's field of vision stopped moving, and the target's rabbit directly levitated, the whole rabbit seemed to become somewhat transparent, and all the organs and structures inside it could be seen with the naked eye. There is a small blank window in the bottom left corner, and I don't know what it is for.

He kept fiddling with the picture with his hand, causing the rabbit to slowly spin. It's just that what should be done? There are no prompts, no buttons, and even now, Xu Wu doesn't know what the so-called genetic modification can do.

Voice operation? I feel that until now, this game seems to be dominated by voice operation.

So what about my goal? The top priority is definitely to improve the intelligence of the rabbit, and what does the improvement of wisdom depend on?

The reason why man can continue to gain an advantage in the competition of nature is that he has intelligence that is difficult for other species to achieve, and this is related to the fact that man has one of the best brains.

But the human brain is not the biggest, and animals like dolphins, elephants, and blue whales are all bigger and heavier than the human brain. That said, intelligence, EQ these do not depend entirely on the size of the brain.

No, it's still an old question, the surface area of the cerebral cortex is definitely not smaller than that of a human being. Even much higher than humans.

It's all brains, where is the difference?

No, no, no, I think too much, what I should do now is to test whether this genetic modification function can be used, how to use it, although brain modification is the ultimate goal, but I should do it after I am familiar with it.

The easiest thing to distinguish is the transformation of appearance. Start with the hair.

Xu Wu stared at the rabbit in a daze for a long time, and finally issued the first command: "Implant the expression gene of melanin in the cells of all hairs." ”

It was only then that the device sounded a warning sound, and Phantom Moon explained beside Xu Wu: "The instructions are not clear, and the gene sequence of melanin is lacking in the gene pool. ”

"How is this!" Xu Wu complained helplessly and angrily.

"Every day the instructions are not clear, who knows what your clear instructions are, and there are no explanations and no examples. It's all a fantasy, how do I know what a standard instruction is? ”

Phantom Moon pointed to the game interface and said to Xu Wu: "This small window seems to be an existing gene pool, you don't see it empty." Owner, are you going to collect genetic information and then conduct your experiments, after all, okay?"

Xu Wu followed Phantom Moon's fingers, looked at the small window, and clicked on it.

After the window was enlarged, Xu Wu saw that the name of the gene bank was written on the window. It really seems to be what Phantom Moon said.

"Don't you know nothing?" Xu Wu asked Phantom Moon, and then immediately regretted it.

"Well, I don't know, but there's a window with a gene pool written on it, and everyone knows what it is, right? I thought the owner of the island had noticed it a long time ago, but I didn't expect it to be unexpected. ”

Phantom Yue's words, like a pig-killing knife, fiercely opened Xu Wu's chest, and poked the heart inside twice, all bleeding.

Not wanting to accept the blow at all, he decided to change the subject.

"I don't know how to collect it, it's really no hint at all. It's like, I want to collect the hair genes of this rabbit, so should I say: It's okay to collect the hair color genes of rabbits?" As soon as Xu Wu's voice fell, the game made a crisp sound, and in the window of the gene pool, there was an additional information box with rabbit hair color genes written on it.

Phantom Moon nodded as a matter of course and said, "Well, that's it, select the target and issue the command." The advantage of the island's operating system is that it is empathetic and easy to understand. ”

Xu Wu looked at the entries that appeared in the gene pool in amazement, and for the first time he had a sense of identity with Phantom Moon's words. It seems to be quite simple. It would be nice to have a little more explanation.

Try to click on the icon of the rabbit hair color gene.

With his movements, the rabbit fur gene icon shattered and turned into a large illustrative diagram. The most striking thing is a map of multiple DNA rotations at the beginning, which constantly rotates, fully embodying the mystery and beauty of biological genes.

Slowly pulling it down, it is the sequence description, and the expression is the base arrangement expression he has learned. TTGACA......

It is written below

Source of genes: Grass hare

Time: August 3, 2019 12:11:20

Sampler: Xu Wu, the owner of the island

Gene 1 functions: control the hair color of grass rabbits, this gene will make rabbit hair yellow.

Gene 2 functions: control the hair color of grass rabbits, this gene will make rabbit hair brown.

......

"Awesome, my island. So, I just need to collect the genes I want, and I'll be able to use them, right? Xu Wu subconsciously clenched his fists, looked at the projection of the gene pool excitedly, and completely fell into excitement.

He first collected all the genes of this rabbit, yes, all, not a single part or detail at all. After adding more genes, he also discovered that the system had a sorting function, that is, he could transform all the genes he collected into another form and store them.

The many genes he collected were integrated into it, allowing him to see them at a glance.

For example, the genes he collected to control the contour of rabbit ears were turned into a rabbit ear, and the genes that controlled the growth rate of rabbit teeth and the expression of rabbit tooth secretions were turned into a single tooth, and all the genes of the whole rabbit were combined into a living grass rabbit in the window of the gene pool.

It just won't move.

When he needs it, he can find the gene he needs and use it right away. In this way, he was relieved that he would have a headache when he was worried that he would see more lists than stars, and he was more bold in collecting genetic information.

From rabbits to cheetahs, from ants, butterflies to chameleons, sparrows. Following the food chain, he kept going through every corner of the island. In the sky and on the ground, those who can fly and swim, he is not ready to let go.

When he saw a rabbit with some black hair, he stopped, and when he saw an antelope with a particularly sharp movement, he went to collect information about its muscles. Wow, this earthworm is very big, is there anything special about its genes?

The feathers of this peacock are particularly beautiful, collect them. Isn't this koi fish so delicious, why do you swim after it?

After collecting more, Xu Wu found again that the genetic sequence of the same species would be classified in one place. For example, all the genes of the grass rabbit were integrated into a rabbit, and at most the source and function of the collection were written in different gene descriptions.

Another finding was that two crocodiles of the same age and different body types did not have much difference in the genes that control muscle and bone growth. To be precise, after constant comparison, Xu Wu didn't find anything different. So, their development is not the same, and it has nothing to do with genes?

Xu Wu didn't understand very well, so he could only record his thoughts and problems first, and then see if he could solve them later.

In the following week, Xu Wu was able to collect the genes of all the creatures on the island. Experiments with rabbit modifications were restarted.

"Alright, old age, let's start with the hair. Xu Wu ordered again energetically.

"Adjustments. ”

Xu Wu found a nest of rabbits again on the grassland and gave the order.

Of course, this is certainly not the rabbit from before. The lifespan of a rabbit is only 5 to 12 years, and even if it does not die, the rabbit has already entered old age. It's no longer suitable for Xu Wu to test.

As usual, Xu Wu still started simple, he enlarged the rabbit's body, and said to the hair: "Recall the hair control gene of the black grass rabbit and implant it into the hair cells and epidermal cells of the rabbit." ”

"Drop!"

The game device sent out a prompt, and through Phantom Moon's explanation, Xu Wu knew that this meant that the command was completed.

It's just that Xu Wu sat and waited, and he didn't see any change in this rabbit, so he hurriedly gave Phantom Moon on the side an inquiring look.

Phantom Moon didn't give him face and said directly with disdain: "Your IQ is really not good, haven't you noticed that when the system is running, the island time is static?

Xu Wu suddenly realized, but he was a little embarrassed to be looked at by Phantom Yue, and his face was bloodshot again, and he was a little red. He explained: "Isn't this a test of whether the Phantom Moon is useful or not? It's not that you don't know, I asked you about the game, and you don't know anything about it all day long." You see, ask you where the game comes from, and you don't know. Ask you how to operate the game, you don't know. Ask you about the archive, and you don't know. Recently, you don't even know how to use this genetic modification. ”

Phantom Moon didn't reply to him as Xu Wu imagined, but fell silent again, as if thinking about something.

Xu Wu, who had withdrawn from the genetic adjustment function, watched the rabbit gradually grow, and suddenly found that the rabbit did not grow into an all-black rabbit as he imagined, only a few hairs grew black hair, and other places were still brown hair.

What's going on? Is it the interaction between genes? Dominic and recessive expression issues like flower color expression?

Xu Wu decided to try again, he went on to select a rabbit and gave the order: "Knock out all the genes of the rabbit about coat color control, and then insert all the genes that control the black hair of the grass rabbit." ”

Xu Wu was pleased to find that the rabbit this time was really an all-black rabbit.

So the black hair is really inhibited by other genes!(Here is what the author said blindly, in reality, I am not very sure about the relationship between the hair color control genes, although it should also be multi-gene control expression, but what is dominant and what is recessive, or whether it is expressed together and affects each other, I am not very sure.) ）

Now that the hair color is successful, let's start experimenting with the others! I'm going to make a rabbit of my imagination. The remaining biomass is enough for me to try many times.

Yes, genetic adjustment requires the consumption of biomass, and the greater the magnitude of adjustment, the more it will be consumed, but it is still the same sentence, Xu Wupiao has been floating recently!
