Which gene is most likely regulated at the posttranscriptional level?
A) Gene A, which shows a strong positive correlation between the amount of mRNA produced and the amount of protein produced
B) Gene B, which shows no clear correlation between the amount of mRNA produced and the amount of protein produced
C) Gene C, which lies near the heterochromatin
D) Gene D, which has more than the typical number of CpG islands
E) Gene E, which has fewer than the typical number of CpG islands

Quizplus · Accepted Answer

Gene B, which shows no clear correlation between the amount of mRNA produced and the amount of protein produced, is most likely regulated at the posttranscriptional level. This indicates that there may be additional regulation occurring after transcription, such as mRNA stability or translation efficiency control. The other answer choices do not provide clear evidence for posttranscriptional regulation.
