Question

DNA molecule segment is: TTACGCAAG
The mutated DNA segment is TTCGCAAG. This is an example of mutation.
Deletion
Substitution
Inversion
Insertion

Answer 1

The mutation from TTACGCAAG to TTCGCAAG is an example of substitution. In this case, the base "A" has been replaced by "C" in the fourth position of the DNA segment.

• Deletion would involve the loss of a base.
• Insertion would involve the addition of an extra base.
• Inversion would entail the reversal of the order of bases.

Since none of these other options apply, the correct answer is substitution.
