Catalytic RNAs, or ribozymes, are a fossil record of the ancient molecular evolution of life on Earth and still provide the essential core of macromolecule synthesis in all life forms today.
A ribozyme (ribo nucleic acid en zyme) is an RNA molecule that can help certain biochemical reactions.similar to the action of protein enzymes. Also called catalytic RNA, ribozymes work in the ribosome to link amino acids during protein synthesis.mproved variants of the Round-18 polymerase ribozyme have been developed. B6.61 is able to add up to 20 nucleotides to a primer template in 24 hours, until it decomposes by cleavage of its phosphodiester bonds. The tC19Z ribozyme can add up to 95 nucleotides with great accuracy.
