Question

A point mutation is shown in the mutated DNA sequence below. Will this mutation affect

Answer 1

My 2 cents below, I tried to think through the other ones:

A. Yes, because an amino acid change has occurred.  

(A gene mutation occurred, not an amino acid change)

B. Yes, because all mutations change the resulting protein.

(Sounds correct. Gene -> mRNA -> protein)

C. No, because the amino acid sequence has not been changed.

(The gene mutation means the amino acid sequence has changed)

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

(They do so)
