What moves in translation?

Explanation:
Translation is driven by the ribosome, and the key chemical step—peptide bond formation between amino acids—is carried out by ribosomal RNA. This RNA component acts as a ribozyme, an RNA molecule that has catalytic activity. So the moving, catalyzing force in translation is the ribosome’s RNA-based active site that stitches amino acids together as transfer RNAs bring them to the ribosome. The other options describe enzymes that aren’t responsible for this process: a general protein enzyme isn’t required for translation’s core chemistry, DNA polymerase handles DNA replication, and lipase breaks down lipids.
