DNA polymerase has an inherent error rate of approximately 10-8, while
RNA polymerase has an error rate of approx. 10-4. A large part of the
difference is due to the lack of prrofreading ability by RNA pol. DNA
pol has the ability to check newly synthesized DNA. If the DNA pol
detects an error, it can back track, excise the error, and correct it.
RNA pol lacks this ability.
