Question

An amino acid codon chart and the base sequence of a non-mutated and mutated mRNA strand are shown below. which mutated mRNA codon would most likely lead to change in the expression of the protein?
. 1
.2
.3
.4​

Answer 1

Answer:

1

Explanation:

I just too the test

Answer 2

Answer:

1.

Explanation:

Remember: the code from DNA to mRNA is

A=U

T=A

G=C

C=G

At the beginning of the sequence of DNA, it was TTA which is suppose to be AAU (or Asparagine), and in the seuquence, the mutated trait was AAC, which is also Asparagine. Thus the mRNA is only changing the expression of the protein not the sequence of DNA (or mRNA)

Hope htis helps!
