Question
Chapter 31, Problem 4P
Interpretation Introduction
Interpretation:
The molecule/catalyst which catalyzed the peptide bond formatin should be delected from the following:
rRNA
A protein in the large ribosomal subunit
A protein in a small ribosomal subunit
Aminoacyl tRNA synthetase
Concept introduction:
Protein synthesis (translation) is a process of generating new protein sequences inside the cell. This process takes place in the cytoplasm of the cell. This process is balanced by the degradation or export of cellular proteins. It is constituted of three steps, initiation, elongation, and termination.
