Question
Chapter 31, Problem 33P
Interpretation Introduction
Interpretation:
The mechanism by which the ribosome identifies the AUG start codon, should be determined.
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 namely, initiation, elongation, and termination.
