DNA Repair Mechanics

DNA is vitally important, but is subjected to abuse through use; various stresses cause considerable hurt. Passing along such seriously damaged DNA to the next generation would lead to a quick extinction of humanity, and wouldn't be much good for other living things, either.

DNA and cells wear out. A 2015 Nobel Prize was awarded for research into the intricate repair mechanisms, inadvertently exhibiting the handiwork of the Creator.

The 2015 Nobel Prize for evolution —

"No, Cowboy Bob. There is no Nobel Prize for evolution."

Oh, right. That's mighty silly of me. Anyway, the 2015 Nobel Prize for chemistry was awarded for research into how cells repair their own DNA. It's not just a matter of enzymes, but also communication of information, and repairs are conducted. This process is clearly from the grace of our Creator, and evolution is impossible.
Tomas Lindahl from Sweden, Paul Modrich from the United States, and American-Turkish researcher Aziz Sancar were awarded the 2015 Nobel Prize in Chemistry for uncovering how cells repair their own DNA.1 DNA repair mechanisms keep us alive, and understanding them undergirds a fuller comprehension of how cells work and fend off the disastrous consequences of too many mutations. The research of these three men implies that cells have always used DNA repair mechanisms, thus uncovering evolutionary mysteries that have not yet found sensible solutions.

Their pioneering work, mostly conducted in the 1970s and 1980s, opened a door to what has become a large research field. Investigators around the world continue to uncover new enzymes and communication networks, including feedback protocols and cellular subroutines, all aimed at protecting DNA. Good thing this happens in every cell on the planet, because otherwise DNA would lose vital information.
