During translation elongation, preloaded tRNA enters one of the sites of the ribosome. Which site is this?
During the ‘elongation’ stage of translation, after the arrival of each new tRNA: A. the amino acid is ‘passed’ from the tRNA in the A site to the tRNA in the P site. B. newly arriving tRNAs must first bind to the E-site. C. the peptide is ‘passed’ from the tRNA in the P site to the tRNA in the A site. D. the new tRNA must first bind to the P-site of the ribosome Hi, i need help with...
Which is correct about the peptide elongation by ribosome? Select one: a. Addition of a new amino acid is achieved by peptide transfer from the A site tRNA to the P site tRNA. b. Translation is not affected by the cellular availability of GTP. c. Peptide bond formation is catalyzed by enzymatic proteins in ribosome. d. The peptide bond is formed by a nucleophilic attack of the A-site NH2- onto the P-site -COOH. e. None of these
42. Which is correct about the peptide elongation by ribosome? Select one: a. Addition of a new amino acid is achieved by peptide transfer from the A site tRNA to the P site URNA. b.

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...
Part A Which of the following statements is NOT true of aminoacyl-tRNA synthetases? They activate the amino acid and covalently bond it to the mature tRNA. They attach the amino acid to the CCA at the 3'-end of the mature tRNA. They attach the amino acid to the elongating peptide and catalyze translocation. Each member of this protein family is dedicated to one particular amino acid. They are primarily responsible for the accuracy of mRNA translation Submit Request Answer Provide...
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...
In eukaryotic systems, which of the following typically stops the process of translation? Select one: a. Rho proteins b. Aminoacyl tRNA synthase c. rRNA d. Stop codons e. Introns
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.
Which is the most inappropriate description of a ribosome? Select one: a. It consists of proteins and rRNAs. b. It has pockets for at three tRNA bindings. c. For initiation, the 30S subunit binds to mRNA before the 50S subunit binds. d. For its translational function, ribosome needs other protein factors. e. Ribosomes carry out translation at consumption of the energy from ATP.
