Which of the following enters the A site of the ribosome? O mRNA tRNA-amno acid amno...
During translation elongation, preloaded tRNA enters one of the sites of the ribosome. Which site is this?
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...
Which of the following does not come in contact with the ribosome? mRNA, RNA , tRNA, DNA
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.
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.
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...
What is the difference between a tRNA entering the A site of the ribosome and a tRNA leaving the exit site of the ribosome?
Which of the following correctly describes the process of Translation? I. tRNA anticodon bonds to mRNA codon II. Ribosome bonds to mRNA strand II. Ribosome reaches a STOP codon and detaches from the mRNA IV. Each tRNA adds an Amino Acid to the chain as the Ribosome moves along the mRNA V. Complimentary mRNA strand is made from DNA template OA. V, I, IV, III B. II, IV, III, I, V C. II, I, IV, III D. V, II, I,...
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)
Place the following steps of TRANSLATION in the correct order for EUKARYOTES. The ribosome reaches a stop codon. A release factor binds and causes the release of the new polypeptide, along with the mRNA. The ribosome dissociates. v Acharged tRNA with a matching anticodon binds the mRNA codon in the A site. ✓ The ribosome moves exactly 3 nucleotides toward the 3* end of the mRNA. The small ribosomal subunit uses rRNA to bind to the Kozak sequence, which places...
