What happens when EF-Tu is mutated? Choose from the options below. Be involved in transcription instead of translation Peptide bond formation is inhibited Incoming tRNA will not be able to enter through the A site Incoming tRNA will not be able to enter through the P site Incoming tRNA will not be able to enter through the E site Translocation is inhibited Hairpin loop formation
Which of the following are stages of translation? Select all that apply. A. A tRNA binds to the second codon and its carried amino acid forms a peptide bond with methionine. B. As the ribosome moves from codon to codon, amino acids brought by successive tRNAs to the ribosome form a growing polypeptide. C. When the ribosome reaches a stop codon, its subunits detach, and the mRNA and new polypeptide are released. D. Ribosomal subunits and a tRNA carrying methionine converge on the start codon of an mRNA. E. The binding of a tRNA to the third codon causes the ribosome to release the first tRNA and move to the next codon.
Which of the following is NOT an event associated with translation termination? A stop codon enters the A site on the ribosome. A Release Factor enters the A site A terminal amino acid is added to the polypeptide to signal the end of translation. Release Factor mediates the hydrolysis of the polypeptide from the tRNA at the P site. The polypeptide and tRNA are released and the ribosomal subunits are separated.
For the following characteristics, state whether they are true for the 5' CAP, the Poly-A tail, BOTH modifications, or NEITHER modification. Briefly (1 sentence) support your answer. Promotes translation of the mRNA at the 3' end. Acts to prevent degradation of the mRNA by exonucleases. Promotes splicing of the mRNA. Promotes binding of transcription factors to the Mediator complex.
