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.
