O Febuary, 2047 answering more. Y A13. Which of the following is an example of a protein that binds to DNA? s comectty a. Peptidyl transferase b. polyA polymerase c. sigma protein d. histone acetylase Capping enzyme A14. How many codons are there that specify tryptophan (W, Trp) a. one b.two , three d' four e.six A15. When translation is initiated, the first amino acylated tRNA is bound to the ribosome a. E site b. P site c A site d. E and P sites e. A and E sites letters growing polypeptide chain STEP T newly bound tRNA H2N 3' 5' ejected tRNA E-site P-site A-site Questions A16, A17 and A18 refer to the picture above. A16. In the picture above, the next step is_ which will then be followed by a. peptide bond formation; termination b. translocation; peptide bond formation c. peptide bond formation; translocation d. translocation; termination e. translocation; ejection A17. The ejected tRNA (number 2) will next a. Be degraded b. Pair with another codon c. Be charged with another amino acid d. return to the A site

Explanation / Answer

A13. Histone acetylase

A 14. Two condons-DNA base triplets- ACC, M-RNA codons-UGC

A15. A site

A16. Peptide bond formation and translocation

A.17 Pair with another codon
