Which of the following is a post-translational modification of a polypeptide?
A
Phosphorylation
B
Translation
C
DNA replication
D
Transcription
Verified step by step guidance1
Understand the concept of post-translational modification: These are chemical changes that occur to a polypeptide after it has been synthesized during translation. These modifications can affect the protein's function, activity, stability, and localization.
Identify the options given: Phosphorylation, Translation, DNA replication, and Transcription.
Recognize that Translation is the process of synthesizing a polypeptide chain from mRNA, not a modification of the polypeptide.
Understand that DNA replication is the process of copying DNA, and Transcription is the process of synthesizing RNA from DNA. Neither involves modifying a polypeptide.
Phosphorylation is a common post-translational modification where a phosphate group is added to a protein, often regulating its activity or function.
