Question

Suppose the following point mutation occurred in the DNA. Will this mutation affect the protein resulting from this gene sequence?


a. Yes, the 5th amino acid in the sequence has changed.

b. No, the amino acid sequence has not been changed.

c. No, mutations in the DNA do not affect the mRNA sequence.

d. Yes, all mutations change the resulting protein.

Answer 1

Answer: Option A) Yes, the 5th amino acid in the sequence has changed.

Explanation:

Absolutely, the change of CCG to CAG does cause the amino acid Proline to be substituted by Glutamine.

Thus, the single base change of cytosine to adenine in CCG and CAG resulted in a different protein.

Answer 2

Answer:

Option A) Yes, the 5th amino acid in the sequence has changed.
