DNA polymerase error rates can be 10-8 to 10° per nucleotide, and mutations in the repair functions of DNA polymerases that increase error rates can cause reduced survival phenotypes. Yet RNA polymerase error rates can be as high as 3 x105. Why is it so much more important for DNA polymerase to be accurate than RNA polymerase? Be brief.

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
