In eukaryotes, control of gene expression is accomplished by
A) translational control in cytoplasm after mRNA leaves the nucleus and before protein is produced.
B) transcriptional control in the nucleus based on which genes are transcribed and how fast they are transcribed.
C) posttranscriptional control in the nucleus after DNA is transcribed, including the speed with which mRNA leaves the nucleus.
D) posttranslational control in the cytoplasm that occurs after protein synthesis.
E) All of the answer choices are correct.

Question

Quizplus · Accepted Answer

In eukaryotes, gene expression is regulated at multiple levels: translational control in the cytoplasm, transcriptional control in the nucleus, posttranscriptional control in the nucleus, and posttranslational control in the cytoplasm. Each of these mechanisms plays a crucial role in determining the final level of gene expression, allowing the cell to respond to various internal and external signals efficiently.
