Expression of some eukaryotic genes can be regulated by translational control. One advantage of translational control is that it
A) provides a means for rapid change in protein concentrations.
B) prevents synthesis of excess RNA.
C) directs proteins to their proper subcellular location.
D) occurs only in zygotes.
E) degrades proteins that are no longer needed.

Question

Quizplus · Accepted Answer

Translational control allows for quick changes in protein concentrations since it controls the rate at which mRNA is translated into protein. This is particularly useful in response to rapidly changing cellular needs or environmental stimuli. Therefore, option A is the best choice. Options B, C, D, and E do not accurately describe the advantages of translational control.
