Post-translational modification may include
A) formation of exons and introns.
B) folding of the protein, often with the aid of chaperones.
C) removal of the signal sequence.
D) addition of glycine tags.
E) folding of the protein, often with the aid of chaperones, AND removal of the signal sequence.

Question

Quizplus · Accepted Answer

Post-translational modification refers to any changes that occur to a protein after it has been synthesized. These changes can include the folding of the protein, often with the aid of chaperones, as well as the removal of any signal sequences. Choice A is incorrect because the formation of exons and introns occurs during transcription when the pre-mRNA is spliced. Choice B and D are incorrect because they refer only to the folding and addition of glycine tags, respectively, and do not take into account other types of post-translational modifications.
