Errors in transcription are not as potentially harmful as errors in DNA replication because
A) many copies of RNA are made.
B) RNA strands have a relatively short life span.
C) RNA polymerases proofread and correct the errors.
D) a and b are correct
E) a, b, and c are correct

Question

Errors in transcription are less harmful because many RNA copies can be made, and they have a short lifespan, so errors do not have lasting effects. RNA polymerases do not have the same proofreading ability as DNA polymerases, so option C is incorrect.
