Scientists have discovered a new way to repair damaged DNA. The chain breaks can be filled with poly-ADP-ribose polymer. This discovery will create a new generation of cancer drugs. This was stated by Academician of the Russian Academy of Sciences Olga Lavrik.
Human DNA can be damaged due to the harsh environment. It is affected by oxidation, ultraviolet light and other environmental pollutants. It restores certain protein assemblies. And it is the polymer that holds them together.
Moreover, scientists have found that it not only holds, but also protects the damaged DNA section before the maturation of the protein constructors. Perhaps this polymer creates a landing site for proteins. Understanding how it works is an important step in managing genome stability, scientists say.
