Eukaryotic regulation of gene expression

The repressor protein for the Protein X gene will stop the transcription of the gene.

The excess Protein X will be tagged with ubiquitin proteins and degraded over time.

The Protein X mRNA will be bound by a microRNA blocking its translation.

Over time the excess Protein X will diffuse out of the cell.

A hormone signal reaches a cell and causes the cell to produce a large quantity of Protein X. After some time, the hormone signal disappears and the cell no longer needs a large quantity of Protein X. How will the cell remove the excess protein?

Regulation of translation

Post-Translational Modifications in prokaryotes and eukaryotes - Types, Functions, and Examples

They inject double-stranded RNA into a cell, turning off a gene with the same sequence.

They encode for products that help prevent uncontrolled cell growth.

No. This refers to tumor-suppressor genes.

They are segments of noncoding DNA that help regulate transcription by binding certain proteins.

No. One of the listed responses is correct.

They are giant protein complexes that recognize ubiquitin and degrade the tagged proteins.

They are involved in protein turnover.

What is the role of proteasomes?

Protein degradation is one strategy to control gene expression and is considered ______.

Post-translational modifications of proteins can affect which of the following?
