Which of the following is an example of post-transcriptional control of gene expression?
A)the addition of methyl groups to cytosine bases of DNA
B)the binding of transcription factors to a promoter
C)the removal of introns and splicing together of exons
D)gene amplification during a stage in development
E)the folding of DNA to form heterochromatin

Question

Quizplus · Accepted Answer

Post-transcriptional control refers to the regulation of gene expression that occurs after transcription has taken place. The removal of introns and splicing together of exons is a common example of post-transcriptional control, as it affects the processing of mRNA before it can be translated into protein. The other choices listed refer to processes that occur during or before transcription, and do not involve post-transcriptional regulation.
