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.

Gene Expression

The process by which information from a gene is used to synthesize functional gene products, often proteins, which can affect the cell's structure and function.

Eukaryotes

Organisms whose cells contain a nucleus and other organelles enclosed within membranes.

Translational Control

The regulation of protein synthesis in a cell by controlling the translation of mRNA into proteins.

  • Outline the mechanisms regulating gene expression at various steps, encompassing transcriptional, posttranscriptional, translational, and posttranslational stages.

Final Answer :
E
Explanation :
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.
