Recently a scientist performed embryonic DNA editing, astonishingly this scientist managed to edit the DNA in baby embryos. This is the story of a scientist who succeeded in editing DNA, see next here.
Sweden, successfully made editing on embryonic DNA. The scientist who succeeded in editing the DNA of a healthy embryo of a mother is Fredrik Lanner. Often he does research to help and improve genetic understanding so that embryonic development can prevent congenital diseases.
Hope from this scientist finally achieved, Fredrik Lanner conducted research that helped in understanding the role of genetics. In fact, he hopes that he can prevent health problems associated with congenital diseases. Until finally, he could help in new discoveries in the medical world.
As a biologist, these developments related to embryo modification made new discoveries in medicine. Even the development of the Karolinska Institute in Stockholm, Sweden. He managed to find a tool that could be used as a genetic engineering tool called CRISPR-Cas9.
Initially Fredrik only planned to be able to research embryo modification at 7 days of development. In fact, he would not allow any progress after 14 days. After going through this research he hopes to identify the influencing genes involved in fertility.
Even the findings made are also expected to help scientists find out about embryonic shoulder cells that can be used as drugs for various diseases. Even to help scientists develop knowledge related to genetic modification.
Thus, among scientists who are concerned about actions that have a negative impact, for example, to insert the wrong gene to create a new disease. This is also very worrying, so that this method requires seriousness and caution.
Chairman of the supervisory group Center for Genetics & Society revealed that when carrying out the process of gene editing in human embryos. Then the gene changes will be made in every cell of the fetal body. Even future generations (mankind) will experience changes. So that it is possible that there will be permanent changes that cannot be changed anymore.
In some countries, genetic engineering in babies is still considered illegal. Even to carry out research using human embryos. Even according to Lanner himself, development and development should be pursued in order to find in-depth research in a further experiment that could be attempted.
It even refers to the results of research from the Proceedings of the National Academy of Sciences (PNAS), which provides an important part about the genome editing tool CRISPR enzyme which can ultimately be used in the cure of diseases related to genetics in humans.
CRISPR’s first discovery of the first found that there were bacteria in the 1980s. Enzymes that have a function as a bacterial immune system against viral invasion. Even scientists have shown that there is a type of CRISPR enzyme, Cas9, which can also edit the human genome.
Now the enzyme has been precisely modified to be able to target letter combinations in the three billion pairs of basic DNA molecules. In fact, this is equivalent to writing errors in 23 volumes of the encyclopedia. The targeting process requires the CRISPR enzyme which can separate DNA strands and also insert RNA to form a specific structure called an R loop.
Thus, the success of DNA editing does not fully bring happiness to the medical world, especially because it is feared that there will be a fatal error related to wrong code editing and new diseases.
