What is the difference between a tRNA entering the A site of the ribosome and a tRNA leaving the exit site of the ribosome?

22) Before the ribosome translocates during elongation, the ribosome's A site contains a tRNA with the site contains a tRNA without an and the ribosome's P After the ribosome translocates, the A site is over the in the mRNA, the P site contains a tRNA with and the E site contains n the mRNA 23) Termination occurs when the ribosome reaches ay sequence. What two molecules are required for termination to occur? 24) What happens to protein after released from...
The only charged tRNA that can enter the P site of the ribosome directly (without coming in through the A site) is the initiator tRNA that recognizes the start codon on the mRNA. This requires precise placement of the mRNA on the small subunit of the ribosome so that the initiator tRNA is opposite the P site binding pocket on the large subunit. Compare and contrast how bacteria and eukaryotes achieve this precise positioning.
Which of the following enters the A site of the ribosome? O mRNA tRNA-amno acid amno acio O tRNA
During translation elongation, preloaded tRNA enters one of the sites of the ribosome. Which site is this?
Which of the following statements about the ribosome is incorrect? The tRNA molecule will move progressively from the E-site, to P-site to A-site. The bond between the amino acid and tRNA molecule is broken at the E-site. O The P-site holds the growing amino acid cha The A site receives the new, incoming tRNA molecule.
Suppose that you have the situation that the P site of the prokaryotic ribosome contains a tRNA to which is attached a peptidyl chain, and the A site contains a tRNA to which is attached an amino acid. What is the next step? A) translocation of the mRNA relative to the ribosome by one codon B) peptide bond synthesis C) dissociation of the tRNA in the P site to allow movement of the tRNA from the A site to the...
During translation, the aminoacyl tRNA would be found positioned in which part of the ribosome? Select one: a. The E site b. The A site c. None of the above d. The P site
During translation, the formation of peptide bonds between amino acids is catalyzed by... ribosome tRNA GTP RNA Polymerase
8) Draw a ribosome in the process of translating an mRNA. A) Label each site. Include information about what state tRNAs are in at each of these sites. (10 points) B) Pick one tRNA in your picture, what kind of bonds is this tRNA forming with other molecules? (5 points)
A ribosome can have as many as three tRNAs associated with it at any given time during translation. Match the following statements with the site in the ribosome where they occur. [Choose ] The initiator tRNA is special because it is the only tRNA that can initially bind at this site in the ribosome. [Choose ] During the elongation stage of translation, new tRNAs enter at which site? [Choose] Peptidyltransferase is the ribozyme that transfers the growing peptide chain from...
