40) What is the function of the release factor (RF)?

A) It separates tRNA in the A site from the growing polypeptide.

B) It binds to the stop codon in the A site in place of a tRNA.

C) It releases the amino acid from its tRNA to allow the amino acid to form a peptide bond.

D) It supplies a source of energy for termination of translation.

E) It releases the ribosome from the ER to allow polypeptides into the cytosol.

Answer:
B) It binds to the stop codon in the A site in place of a tRNA.

    42) Suppose that a mutation alters the formation of a tRNA such that it still attaches to the same amino acid (phe) but its anticodon loop has the sequence AAU that binds to the mRNA codon UUA (that usually specifies leucine leu).

    A) The modified tRNA will cause this mRNA to make only nonfunctioning product.

    B) The tRNA-leu will not be able to enter the site of the ribosome to bind to the UUA.

    C) One mutated tRNA molecule will be relatively inconsequential because it will compete with many "normal" ones.

    D) The tRNA will be so unstable that it will not participate in translation.

    E) The mutated tRNA will result in an amino acid variant in all copies of the protein.

    C) One mutated tRNA molecule will be relatively inconsequential because it will compete with many "normal" ones.

    43) Why might a point mutation in DNA make a difference in the level of protein's activity?

    A) It might result in a chromosomal translocation.

    B) It might exchange one stop codon for another stop codon.

    C) It might exchange one serine codon for a different serine codon.

    D) It might substitute an amino acid in the active site.

    E) It might substitute the N-terminus of the polypeptide for the C-terminus.

    44) In the 1920s Muller discovered that X-rays caused mutation in Drosophila. In a related series of experiments in the 1940s, Charlotte Auerbach discovered that chemicals–she used nitrogen mustards–have a similar effect. A new chemical food additive is developed by a cereal manufacturer. Why do we test for its ability to induce mutation?

    A) We worry that it might cause mutation in cereal grain plants.

    B) We want to make sure that it does not emit radiation.

    C) We want to be sure that it increases the rate of mutation sufficiently.

    D) We want to prevent any increase in mutation frequency.

    E) We worry about its ability to cause infection.

    D) We want to prevent any increase in mutation frequency.

    C) a substitution of the third nucleotide in an ACC codon

    D) a substitution of the first nucleotide of a GGG codon
