The rate of translation can be slowed drastically when a ribosomal protein is phosphorylated in response to a sudden temperature increase or viral infection.In this case,the phosphorylated ribosomal protein is under ________ control,and the phosphorylation of this ribosomal protein leads to widespread ________ control.
A)transcriptional;translational
B)translational;post-translational
C)post-translational;transcriptional
D)post-translational;translational
E)transcriptional;post-translational

Question

Quizplus · Accepted Answer

The phosphorylation of a ribosomal protein is a post-translational modification, which is indicated by choices B, C, and D. However, the fact that this modification leads to a slowdown in translation suggests that it is under translational control, which rules out choices A and E. Therefore, the best choice is D, post-translational and translational control.
