Option c. During elongation preloaded tRNA enters the ribosome A site.
Ribosome has 3 binding sites- A, P and E (Therefore, ruling out option 2). At A site, the incoming preloaded tRNA (amino-acyl tRNA) enters and binds with the codon of the ribosome. The tRNA carrying the growing polypeptide chain is then translocated to the P site , whereas the E site carries the empty tRNA before it leaves the ribosome.
Therefore the correct option is C.
During translation elongation, preloaded tRNA enters one of the sites of the ribosome. Which site is...
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...
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
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
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 of the following enters the A site of the ribosome? O mRNA tRNA-amno acid amno acio O tRNA
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. Translation is not affected by the cellular availability of GTP. O c. Peptide bond formation is catalyzed by enzymatic proteins in ribosome. O d. The peptide bond is formed by a nucleophilic attack of the A-site NH2- onto the P-site -COOH. O e. None of...
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...
can someone check my work? 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. P site The initiator tRNA is special because it is the only tRNA that can initially bind at this site in the ribosome. During the elongation stage of translation, new tRNAs enter at which site? A site Esite Peptidyltransferase is the ribozyme that transfers...
Determine whether the following events occur during initiation, elongation, or termination. Initiation Elongation Termination in prokaryotes, the Shine-Dalgarno sequence pairs with rRN translocation occurs kinetic proofreading occurs IF2 dissociates an aminoacyl-tRNA enters the A site ribosome recycling factor displaces deacetylated tRNA from P site in E. coli, an initiation factor blocks the A site
for part 1 and 2 answers are either A,E, or P site for the next 2 its codon/anticodon and then gtp hydrolysis/peptide bond formation, then last one is eithe A/E/P During the process of translation elongation, the tRNA bound to the polypeptide chain is bound in the ribosome at the [Select] . and the tRNA carrying the next amino acid enters at the [Select] . If the [Select] on the tRNA matches the [ Select ] on the mRNA, the...
