Document Summary

All credit goes to freeman biology 6th edition 2017. Ribosomes- site of protein synthesis, using genetic info from mrna. Was strong correlation b/w # of ribosomes and protein synthesis rate. Polyribosome- mrna molecule translated by 2 or more ribosomes(allows many copies of proteins from single mrna). Adapter molecules hold amino acids in place, allow for direct interaction(h-bonding) with mrna codon(chemical go between). If no adapter molecule, then side chains of amino acids couldn"t bind with mrna nucleotides as well. 17. 4: the structure and function of transfer rna. Transfer rna(trna)(adapter molecules)- l-shaped rna molecule, w/ anticodon on one end, and amino acid at other end, has specific amino acid binding to corresponding codon in mrna in translation. Amino acids are transferred from trnas to proteins. Cca sequence at 3" end of 2ndary structure of trna is site for attachment of a. a. Aminoacyl trna- trna linked to amino acid. Anticodon- three bases in trna binding to mrna codon w/ complementary sequence.
