Question

Frameshift mutations result from the: a. insertion or deletion of one or two base pairs. b. substitution of a stop codon for an amino acid-specifying codon. c. substitution of a start codon for an amino acid codon. d. substitution of one base pair for another. e. substitution of more than one base pair. Following peptide bond formation between the amino acid in the A site on the ribosome and the growing polypeptide site: a. moves to the P site of the ribosome. b. forms a covalent bond with the P site of the ribosome. c. releases the growing polypeptide chain. d. picks up another amino acid to add to the chain. e. forms a peptide bond with A site of the ribosome. RNA is _____ and contains the nitrogenous base _____, which is absent in DNA. a. single-stranded; thymine b. double-stranded; c. single-stranded; d. double-stranded; thymine e. single-stranded; cytosine RNA polymerase binds to the promoter sequence in RNA. True False

Explanation / Answer

32. The answer will be a.insertion or deletion of one or two base pairs becuase in frame shift mutation base pairs are added or deleted.it is of two types: inframe and out frame.in inframe base pairs are added and in out frame base pairs are deleted.

33. The answer will ne a

34. The answer is c as it is single stranded and contains uracil in place of thymine

35. It is false because RNA polymerase binds to the promoter site of DNA and perform transcription.
