WebDNA damage and repair Maintaining the genetic stability that an organism needs for its survival requires: 1. An extremely accurate mechanism for replicating DNA, 2. Many mechanisms for repairing the many accidental lesions or damages that DNA continually suffers. The importance of DNA repair is evident from the large investment that cells … WebProkaryotes have fewer genes and these genes are all located on one chromosome. Groups of genes producing proteins with related functions are often organized into operons in prokaryotes but not in eukaryotes. Eukaryotes also have mRNA that must have its introns excised and the mRNA transported out of the nucleus to the ribosomes. camp wright colinton ab
