Another tRNA has to attach to the A site before the peptide chain can be hydrolyzed from the P site and moved to the A site tRNA (FA 2020 pg 45)
fataldoseAs the Peptide chain is transfered to the tRNA at the A site, the ribosome moves down the mRNA moving the now empty P site tRNA to the E site, and the tRNA from the A site to the P site, making room for the next amino acid charged tRNA to attach to the A site.
The translation comes to an end when a releasing factor recognizes one of the stop codons (does not code for an amino acid), which then catalyzes the release of the peptide chain from the tRNA in the P site.
Peptidyl transfer to E site is wrong because peptidyl tranfer occurs between P site to the A site, not to the E site
eIF4E is a eukaryotic translation initiation factor involved in directing ribosomes to the cap structure of mRNAs. Once methionine charged tRNA locates the start codon, all initiation factors are released.+62020-05-05T23:52:12Z
