Answer 2

Answer:

Ribozymes are catalytically active RNA molecules or RNA–protein complexes, in which solely the RNA provides catalytic activity. The term ribozyme refers to the enzymatic activity and ribonucleic acid nature at the same time. Ribozymes are found in the genomes of species from all kingdoms of life.

Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U).
