The US supercomputer Summit can make an amazing 200,000 trillion moves every second. This enormous power allowed scientists at Georgia State University to study how DNA repairs itself. They used a tool called NAMD to look at something called the ‘pre-incision complex’, which is very important for fixing damaged DNA. This big discovery helps us understand how molecules work inside our bodies.
Summit helps us see how DNA repairs itself and shows how important mutation spots are for damage.
The scientists ran long simulations to watch the tiny movements of molecules over a microsecond—a very quick time! They saw how proteins like XPC find damage in DNA and fix it. The head scientist, Ivaylo Ivanov, said that if there are changes, or mutations, in certain areas, it can mess up this repair and lead to serious genetic illnesses.
Important PInC dynamics show unique patterns of mutations and places where repairs could fail.
After Summit’s six-year run, they will switch to a new, even more powerful supercomputer named Frontier. Next, they will study how DNA repair works in active genes to keep them safe. This progress in studying DNA with computers can help create new treatments and lessen the bad effects of DNA changes. So, scientific research is leading the way to make things better in the future!
Conclusion
Recap of Key Points: The US supercomputer Summit helps scientists understand how DNA repairs itself. They found that tiny proteins fix damage in DNA with great detail.
