What is DNA?

DNA is the basis of our existence. It carries our, and all living life form’s genetic information. It is found in every single cell in our body, and is needed for growth and reproduction. Our DNA is generated naturally, and our bodies depend on it to survive. Our DNA also defines our traits and characteristics. It determines who we are. However, have you ever thought of the possibilities if we could control this at will?

What’s New?

Recently, the first ever case of successful AI designed DNA was reported. The designed synthetic molecule was actually able to successfully control gene expression in healthy mammalian cells! To test it, the scientists asked the AI to make “synthetic fragments that activate a gene coding for a fluorescent protein in some cells while leaving gene expression patterns unaltered”. They tested these fragments in mouse blood, and the fragment fused with the genome at random locations. The experiment was considered a success, which means that many new possibilities have opened up!

New Innovations

The AI tool was created by researchers at the Centre for Genomic Regulation, also known as CRG. The tool creates DNA regulatory sequences that did not exist before. How it works is that it predicts which combination of DNA letters (A, T, C, G) are needed for the gene expression patterns required, then researchers chemically synthesize the DNA fragments and add them to a virus for delivery into cells. Apparently, this tool can also create custom fragments of DNA; for example, you can tell it to switch a certain gene on only in stem cells that turn into red-blood-cells. 

Hope for the Future

This new technology is extremely beneficial for our future. Since many diseases stem from faulty gene expression, it could help researchers find new ways to treat illnesses and diseases, and can help “fine-tune” a patient's genes, in order to make treatments more effective, or to reduce the side-effects of certain treatments. Now that the technology has been proven to work in practice, the researchers are starting to work towards larger-scaled research, in order to further develop and apply this technology. Who knows? Maybe in the future, this technology will save thousands of people. We can only wait and see.
