Homework Answers
1. initiator tRNA initally binds at p site. A site and E site remain occupied by initiating factors.
2. during elongation new tRNA enters at A site. A site contain all the charged tRNA.
3. In A site, all the new charged tRNA comes. So peptidyltransferase is the ribozyme that transfers the growing pepetide chain from the tRNA in the P site to the charged tRNA at Asite.
4. empty tRNA will move toward the E site. see the figure of events in translation.
5. release factor terminates the translation by recognizing the stop codon in mRNA at A site.

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...

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.

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...

18) A mutation occurs such that a spliceosome cannot remove one of the introns in a gene. What effect will this have on the gene? Translation will continue, but a nonfunctional protein will be made b) Translation will continue and will skip the intron sequence c) It will have no effect; the gene will be transcribed and translated into protein d) Transcription will terminate easily and the protein will not be made 19. During the process...

15. Translation (RNA protein) has three main stages: initiation, elongation, and termination. a. Initiation occurs when the small ___________________ subunit binds to the ____ end of mRNA and is then joined by the large _________________ subunit (which has three sites called the A, P, and E sites). Once the complex is formed, the _______________ begins to read the mRNA in a ____ to ____ direction. When it reaches the first start codon (_________) a tRNA carrying the amino acid ______________________...
