Question

Refer to the figure showing the potential points for the regulation of gene expression.  Which point would not be considered posttranscriptional control?

Quizplus · Accepted Answer

Point 1 refers to the initiation of transcription, which is not posttranscriptional control. Posttranscriptional control happens after the RNA has been produced, such as alternative splicing, RNA editing, and regulation of mRNA stability and translation. Points 3, 4, 5, and 6 all involve posttranscriptional control, such as mRNA processing, transport, stability, and translation.
