Question

Post-translational control refers to: a. regulation of gene expression after transcription b. regulation of gene expression after translation c. control of epigenetic activation d. the period between transcription and translation

Short answer

Option b is correct.

Step-by-step solution

Step 1. Introduction

Gene expression can be regulated at any stage like transcription, processing of pre-mRNA to mature mRNA, transportation of mRNA from the nucleus to the cytoplasm, translation, and post-translation.

Step 2. Explanation of the correct option

Option b is correct because Post-translation control is a mechanism by which the protein structure is altered after translation. The post-transcriptional process involves modification of pre-mRNA such as capping, splicing, and polyadenylation in the nucleus. It is a regulation of the gene expression after the translation process or the formation of protein.

Step 3. Explanation of the incorrect options

Option a is incorrect because post-translation control refers to the regulation of gene expression after translation.

Option c is incorrect because post-translation control refers to the regulation of gene expression after translation.

Option d is incorrect because post-translation control refers to the regulation of gene expression after translation.
