Answer

Correct option: D.
$\text{RNA}$ acting as enzyme.
A ribozyme is an $\text{RNA}$ molecule with a well$-$defined tertiary structure that enables it to act like a protein enzyme in catalyzing biochemical and metabolic reactions within a cell.
These $\text{RNA}$ molecules are enzymes that are not composed of proteins.
Ribozymes function as part of the large subunit ribosomal $\text{RNA}$ to link amino acids during protein synthesis.
