The expression of some genes can be regulated in part by the pattern of RNA splicing.This is an example of
A) DNA methylation.
B) transcriptional regulation.
C) pretranscriptional control.
D) posttranscriptional control.
E) genomic imprinting.

Question

Quizplus · Accepted Answer

RNA splicing occurs after transcription and is therefore a posttranscriptional control mechanism. It can affect the final mRNA product and ultimately the protein that is produced from that mRNA. DNA methylation, transcriptional regulation, pretranscriptional control, and genomic imprinting all occur at the level of transcription or earlier in the process.
