Question

A gene has a base sequence of GTC. Due to mutation, the base sequence changes to GTG. Answer the follow questions

a) what are the bases of mRNA coded for this section of DNA, before the mutation?
c) what amino acid is coded by this section before the mutation?
d) what amino acid is coded by this sequence after mutation?

Answer 1

The answer will be a)

Answer 2

i only have a few of the answers

Step-by-step explanation:

a) What are the bases of mRNA coded for by this section of DNA, before the mutation? Hint: In RNA,

A pair with U. (1 point) CAG.

b) What are the bases of mRNA coded for by this section of DNA, after the mutation? Hint: In RNA, A

pairs with U. (1 point) CAC.

c) What amino acid is coded for by this sequence before the mutation? Hint: Use the codon table. (1 point) Glutamine.

d) What amino acid is coded for by this sequence after the mutation? (1 point) Histidine.
