Chapter 16: Q. 19 (page 415)

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

a. protein function

b. transcriptional regulation

c. chromatin modification

d. all of the above

Short Answer

Expert verified

Option a is the correct answer

Step by step solution

01

Introduction

Proteins can be chemically altered by adding groups like acetyl, methyl, phosphate, and ubiquitin. Proteins' activity or how long they stay in the cell depends on the presence or absence of these groups. Sometimes, these alterations can control a protein's location within a cell, such as in the cytoplasm, the nucleus, or linked to the plasma membrane.

02

The explanation for the correct answer

Posttranslational modifications (PTMs) are covalent processing activities that, through proteolytic cleavage and the addition of modifying groups to one or more amino acids, alter the characteristics and functionality of a protein.

03

The explanation for the incorrect options

The stability, decomposition, or functionality of the protein may be significantly impacted by these post-translational alterations. So, the rest of the options are irrelevant.
