Question

Quizplus · Accepted Answer

A ribozyme is an RNA molecule with catalytic activity. It is capable of catalyzing a chemical reaction, just like an enzyme made of protein. Ribozymes were first discovered in RNA viruses, but they are also found in some cellular processes, such as some types of RNA splicing.
