GEN-3000 Chapter Notes - Chapter 13: Hydrolysis, Prokaryotic Small Ribosomal Subunit, Release Factor
Document Summary
Eukaryotes transcription in the nucleus, translation in the cytoplasm. Prokaryotes don"t have a nucleus so it all occurs in the cytoplasm. Ribosomes, the protein synthesis machines, are made up of protein and rna. Ribosomes rrna complex with proteins to form ribosomes. Ribosomes do all the protein synthesis in the cell, they are essential. Large subunit and small subunit work together to form final ribosome, so several different types of rrna. Prokaryotic units are smaller than in eukaryotes 70s vs 80s (80 is bigger). But they both still have small and big subunit. Ribosomal rnas are part of the protein synthesis machine. More rrna in our cells than any other type of rna when the ribosomes are formed they have 3 important pockets: a site, p site and e site. Also has mrna binding site. mrna site is where all of the process of translation takes place. Divided into stages: binding of amino acids to trnas, initiation, elongation, termination.
