How many trna molecules can a ribosome hold

Web10 apr. 2012 · Of course, the length (and thus the mass) of an mRNA varies quite a lot, so it would seem likely that sometimes it's the ribosome that moves mostly, sometimes it's the mRNA, and sometimes it's both. Also, as shigeta and others have pointed out, there can be more than one ribosome attached to the same mRNA strand. Web10 jul. 2024 · Three processes are required: (1) replication, in which new copies of DNA are made; (2) transcription, in which a segment of DNA is used to produce RNA; and (3) translation, in which the information in RNA is translated into a protein sequence. Replication New cells are continuously forming in the body through the process of cell division.
