Mutations in sequences that are removed from the primary RNA transcript never affect RNA processing.

Question

Quizplus · Accepted Answer

Mutations in sequences that are removed from the primary RNA transcript can affect RNA processing, as these sequences may contain important regulatory elements or splicing sites that are necessary for proper RNA processing. Mutations in these sequences can therefore result in aberrant splicing or inefficient RNA processing, which can have downstream effects on gene expression and cellular function.
