Hilbo''s words, like a thunder, rang in the minds of all the students!


    Put everyone under control!


    Everyone looked at the teacher and couldn''t speak for a long time


    They couldn''t believe it. The teacher said it himself.


    I can''t believe it''s true!


    Mary Claire couldn''t help saying, "teacher... Are you... Kidding!?"


    Hilbo smiled and shook his head: "I''m not kidding!"


    "This research is no longer necessary."


    "Why?" Mary Claire''s face changed.


    Hilbo sighed faintly: "you see, I just simulated the production process of insulin-like growth factor 2, a polypeptide composed of 67 amino acids, and found it difficult to achieve accurate separation, or even... Impossible at all!"


    "The gene of insulin-like growth factor 2 is located on chromosome 11p15.5 next to the insulin gene. Their span is 30kbigf2. Do you know what it means?


    This shows that the gene initially synthesized the proinsulin-like growth factor 2 protein precursor, which is composed of A-E domain and a 24 residue signal peptide! "


    "I just used the latest crisprcas9 gene editing technology, and then combined the traditional ZFN and talen technology. I can say that I have used all the means I can use!"


    "But... Still can''t do accurate separation!"


    "It seems that there is only one or two free radicals at a time, but it is really different!"


    "I speculate that Chen Cang''s gene cutting means are far above me!"


    "Crisprcas9 is actually defective... He can''t cut without PAM in front of the target, and the specificity is not high. Therefore, I speculate that Chen Cang may only use traditional restriction endonuclease!"


    "If so, the amount of endonuclease he has... Is far more than ours!"


    Mary Claire was stunned at the sound


    How is that possible?


    "It''s impossible, sir... We have nearly 5000 kinds of restricted endonuclease, which was discovered when China attended the meeting last year..."


    "Moreover, we also have crisprcas9 technology. This is our most advanced technology. We use cas9 protein! Chen Cang..."


    Mary Claire can hardly believe this fact!


    Chen Cang is just a surgeon. How can he be proficient in genetic engineering?


    and!


    How old is he? He''s under 30!


    Can''t I compare with him in the research of his poor life?


    Proud as Mary Claire, it''s hard to accept this fact!


    However, her teacher''s words broke all her confidence!


    Hilbo glanced at Mary Claire and said faintly, "do you think Chen Cang won''t use crisprcas9 technology? That''s because you haven''t reached the back of this experiment. You may not see that at the last point, you see, when the editing techniques were finally combined, Chen Cang used three editing techniques to edit at the same time!


    At the same time!


    It is to use three methods at the same time, act on three different targets, and edit at the same time, so as to ensure the unity of time and editing order! "


    "This shows that Chen Cang''s attainments in the use of crisprcas9 technology are much better than me!"


    Speaking of this, hilbo was lonely, and the pride of 80 years disappeared!


    What genius?


    What glory?


    What achievements?


    Maybe there are some geniuses in this world. They never care about fame and wealth, but they hide treasure!


    Chen Cang, what kind of person are you!


    Mary Claire and everyone around looked at hilbo and didn''t expect the teacher to say such a thing!


    For a time, several students were silent!


    This time, in order to help Mary Claire carry out the research, hilbo called several students.


    These people are the world''s top experts!


    But now


    Are silent!


    Mary Claire couldn''t help asking, "is there really no way?"


    Hilbo shook his head. "Let me give you some advice."


    "Now, while it''s still early and the impact has not expanded, my suggestion is to contact Chen Cang for optimization!"


    "I think since he can study the mechanism of insulin-like growth factor 2, it will only be a matter of time!"


    "It''s not impossible to wait until you conquer it yourself, but... The time cost may be very high!"


    Hilbo continued: "if I''m not wrong, it''s not a drug problem, but it''s also a drug problem!"


    "In the final analysis, the general direction of your research plan is right, but the small details are not handled well."


    "If the treatment of African Americans by drugs is not handled well, this matter can be infinitely magnified!"


    "Go back quickly and see what they say. I''m tired, too!"


    With that, hilbo turned and left.


    Before leaving, I suddenly remembered something and quickly told me:


    "And... Don''t provoke Chen Cang!"


    Several students looked at a strange person like a proud teacher, Mr. hilbo, who had never served a person in his life, and even said such words!


    it happens that there is a similar case!


    Karimos contacted experts in the field of genetic engineering at Johns Hopkins University and MIT to start research!


    But!


    The results are surprisingly consistent!


    No one can go down.


    This matter is no longer a matter of ability. It is called a technological fault, also known as the natural cutting of science and technology!


    They know very well that there is still a great distance to reach Chencang!


    For a moment, two top scientists said to karimos:


    "Mr. karimos, I''m sorry, we did our best!"


    "That''s right! But... Professor Chen Cang''s genetic engineering means are far better than ours!"


    "Maybe after today, we need to go to China for a study!"


    "Yes!"


    "Unexpectedly, Professor Chen, an expert in medical surgery, has such a profound understanding of genetic engineering!"


    Karimos is silent!


    He didn''t expect such a thing to happen.


    Karimos hesitated for a long time and had to wait for the good news from Mary Claire. Maybe professor hilbo... There is still hope!


    "Professor karimos, you can find professor hilbo. Maybe he has means!"


    The voice is still here!


    Karimos''s phone rang.


    His eyes lit up when he saw that the phone was from Mary Claire.


    But!


    The next few words of Mary Claire completely silenced karimos.


    Is there really no way?


    Karimos is dead!


    Experts from Johns Hopkins University and Massachusetts Institute of technology could not help cooling their hearts when they saw karimos like this.


    It seems that Professor hilbo has no choice!


    At this time, China!


    Chen Cang is anxious!


    no way!


    You can''t delay any longer. If you go on like this, you can''t finish your task.
