Elongation Cycle, Step III: Translocatione P site (Fig. 12.1, .). . is defined as an intraribosomal movement of the bound tRNA residues accompanied by the shift of the template polynucleotide relative to the ribosome. In sum, the tRNA residue of the peptidyl-tRNA moves from the A site to the P site, the deacylated tRNA is displaced from th

Termination of Translationne of these triplets possess a cognate aminoacyl-tRNA; they all stop translation. Thus, they serve as . (Brenner, Stretton, and Kaplan, 1965; Brenner ., 1967). UAA is the most frequently used of these codons, whereas UAG is rarely used.

Initiation of Translatione, or reinitiation of translation of the next coding sequence of the same polycistronic mRNA (in prokaryotes), or reinitiation of translation of the same monocistronic mRNA (in eukaryotes) by vacant post-termination ribosomes have evolved in living matter.

The progress continues, and readers should be prepared that some facts, statements, and ideas includ

Mutual Arrangement of Ribosomal RNA and Proteins (Quaternary Structure)eases. This fundamental difference compared to viral particles is understandable, since the ribosome is a functional structure in which RNA should actively participate in interactions with external factors, and is not used for storing genetic information.
