How are ribozymes different from enzymes
Web27 de fev. de 2024 · Ribozymes are RNA enzymes that catalyze certain biochemical reactions, such as in the aminotransferase activity of the ribosome and in the cleavage (or ligation) of its own or another RNA. They are also observed to participate in viral replication. Ribozyme occurs within the ribosome. Ribosomes are biomolecules in the cytoplasm … WebRibozymes are the catalytic RNA (rRNA or Ribosomal RNA) discovered by Sydney Altman and Thomas Cech in the 1980s. They demonstrated that an RNA called Ribonuclease P cleaves the precursor tRNA to form functional tRNA. This RNA or the Ribozymes are the non-protein enzymes. …. So, the correct answer is ‘Ribozyme’.
