Question

1. A mutation that causes changes in the amino acid sequence downstream of the mutation is called

a point mutation.
a translocation mutation.
a substitution mutation.
a frameshift mutation.
2. What will be the outcome of deletion of the third base, A, from the DNA sequence below? Assume that the first base corresponds to the start of a codon. (1 pt) (original)
-C-C-A-A-A-T-A-A-A-G-

The first amino acid in this sequence does not change.
A frameshift mutation occurs.
Gly-leu-phe is changed to gly-tyr-phe.
All of the above are correct.

Answer 1

1. The correct response is a frame shift mutation

2. I believe the correct response is all of the above.

Answer 2

A frameshift mutation to chromosomes will cause the amino acid sequence after the mutation to change. Most likely all of the above are correct for the second question.
