Question

Which of the following important biochemical reactions in living systems is catalysed by a ribozyme?

Answer 1

Ribozymes are present in different shapes and sizes and they help in catalyzing the cleavage and ligation of the phosphodiester bonds in their cis and trans forms.

Within the ribosome, ribozymes function as part of the large subunit ribosomal RNA to link amino acids during protein synthesis. They also participate in a variety of RNA processing reactions, including RNA splicing, viral replication, and transfer RNA biosynthesis.

These enzymes specially help in the peptide bond formation at the time of the protein synthesis with the help of ribosomal RNA.

Hence, the correct answer is option “C” - Formation of peptide bond.
