Chapter 16: Q. 15 (page 415)

Which of the following are involved in posttranscriptional control?

a. control of RNA splicing

b. control of RNA shuttling

c. control of RNA stability

d. all of the above

Short Answer

Expert verified

Option d is correct.

Step by step solution

01

Step 1. Introduction

The post-transcriptional process involves modification of pre-mRNA such as capping, splicing, and polyadenylation in the nucleus.

02

Step 2. Explanation of the correct option

Option d is correct because post-transcription involves control of RNA splicing, shuttling, and stability are involved. The post-transcriptional modification involves capping, splicing, and tailing. It is a regulation of gene extraction after the translation process is completed.

03

Step 3. Explanation of the incorrect options

Option a is incorrect because in post-transcription control of RNA splicing, shuttling, and stability are involved.

Option b is incorrect because in post-transcription control of RNA splicing, shuttling, and stability are involved.

Option c is incorrect because in post-transcription control of RNA splicing, shuttling, and stability are involved.
