DNA, Entropy and Ordering

Post by precisionart » Tue May 01, 2012 6:50 pm

It seems that dna is constantly taking on damage - entropy. Why doesn't this damage accumulate over time? It appears that the amount of genetic damage that should accumulate would significantly outweigh the amount of ordering produced from the basic mechanisms of evolution. How is DNA ordering sustained over time? Is there a process of 'healing' or re-ording?

In short, how do they function and restore lost information?

Imagine you have a book, but you loose one page from it. How would you restore it?
