PPT-Lecture 8 :Protein synthesis

TRANSLATION Initiation Elongation and Termination of Protein Synthesis in Eukaryotes Initiation Initiation of protein synthesis differs significantly between prokaryotes and eukaryotes Eukaryotic mRNA has no ribosomebinding site RBS Instead recognition and binding to the ribosome . 1 Lecture 5 1 INITIATION Assembly of active ribosome by placing the first mRNA codon AUG or START codon near the P site and pairing it with initiation tRNA fMettRNA fMet Occurs once per polypeptide chain or molecule 2 ELONGATION Involves three disti GO TO .
