Answer 1

The mutation illustrated between the two DNA sequences is a substitution mutation.

In the provided sequences, the wild type sequence is "TTGACTCGGTATAC," and the mutant sequence is "TTGACTCGTATAC." The difference is that in the mutant sequence, one base (the letter "G") has been changed to another base (the letter "T") at the same position. This is characteristic of a substitution mutation, where one nucleotide is replaced with another.
