Ribosome Elongation by Tu/Ts and EF-G

The video tutorial explains the process of elongation in ribosomes, focusing on both prokaryotic and eukaryotic systems. It details the role of G proteins like EF-Tu and EF-G in facilitating tRNA binding and ribosome translocation. The formation of peptide bonds is catalyzed by ribosomal RNA, specifically peptidyl transferase. The tutorial also covers the cycle of elongation, highlighting the movement of tRNA through the ribosome's sites and the continuous growth of the peptide chain.

What happens to the tRNA in the P site after the peptide bond is formed?

How does the EFG protein facilitate ribosome translocation?

Discuss the significance of the hydrolysis of GTP in the elongation cycle.
