A) The increased efficiency of proofreading repair in transcription and the large numbers of RNA sequences produced
B) The increased efficiency of proofreading repair in transcription and the reduced lifespan of RNA sequences
C) The reduced lifespan of RNA sequences and the large numbers of RNA sequences produced
D) The large numbers of RNA sequences produced and the fidelity function
E) The fidelity function and the increased efficiency of proofreading repair in transcription

Question

Quizplus · Accepted Answer

Errors in transcription are less harmful than errors in DNA replication because RNA sequences have a shorter lifespan and are constantly being produced in large numbers, meaning that any errors will likely be eliminated as the RNA is degraded and/or replaced by freshly produced sequences. Since RNA sequences are not replicated in the same way as DNA, there is no fidelity function and proofreading repair is less efficient in transcription.
