Final answer:
Ribozymes are RNA molecules that catalyze chemical reactions in organisms. They are involved in various biological processes such as RNA splicing, replication, and translation. Ribozymes play a crucial role in both prokaryotes and eukaryotes.
Step-by-step explanation:
Ribozymes are RNA molecules that catalyze chemical reactions, similar to enzymes. They are involved in various biological processes such as RNA splicing, replication, and translation. Ribozymes play a crucial role in both prokaryotes and eukaryotes, and their activity has been observed in retroviruses as well. For example, ribozymes can catalyze reactions that lead to the removal of introns from pre-mRNA during RNA splicing.
