Question
Chapter 31, Problem 36P
Interpretation Introduction
Interpretation:
The advantage of protein synthesis taking place on polysomes should be determined.
Concept introduction:
Polyribosome, also termed as polysomes, is a complex of two or more ribosomes attached to an mRNA strand, which is going under translation process. It can be of two types, free polysomes, and membrane-bound polysomes. These two forms differ in the presence of polyadenine and non-polyadenine sequence.
