Ribozyme is an

Ribozyme is an RNA molecule functions as an enzyme, Enzymes that add the 5' cap and poly a tail to m RNA, and Protein causes RNA splicing.
A ribozyme is an 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.
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.
