DNA is the genetic library of the cell, while RNA transports, translates and controls the expression of that information. DNA must be copied with unprecedented accuracy once every cell cycle. It is under constant endogenous and environmental onslaught, and a variety of repair pathways are necessary to maintain the integrity of the genetic blueprint. DNA is the only cellular molecule for which repair occurs to a significant extent. DNA undergoes recombination, a kind of molecular cut and re-join that creates diversity to facilitate evolution, as well as providing an important repair pathway. In eukaryotes something like 2m DNA is packaged into chromosomes so that it packs into the cell nucleus with a diameter of just 6 m, while remaining accessible to the cellular machinery that reads out its genetic information
