Formation of peptide bond between amino acids during translocation is catalyzed by __________.
Options:
Answer:
A
Solution:
During translation, the formation of a peptide bond between amino acids is catalyzed by the enzyme peptidyl transferase.
Peptidyl transferase is an integral part of the large ribosomal subunit. In prokaryotes, it is the 23S rRNA, and in eukaryotes, it is the 28S rRNA.
Since it is an RNA molecule that acts as an enzyme, it is known as a ribozyme.
Polynucleotide phosphorylase is an enzyme that synthesizes RNA without a template.
Permease is a membrane transport protein that facilitates the entry of lactose into the cell.
Transacetylase is an enzyme involved in the lac operon.
Answer: Ribozyme
