Answer 1

The DNA sequence AATC is represented by the STR analysis tool, which is used to compare specific regions of DNA between individuals.

Step-by-step explanation:

The DNA sequence AATC is represented by the STR analysis tool. Short Tandem Repeat (STR) analysis is a technique used to compare specific regions of DNA between individuals. It involves amplifying and analyzing the number of repeats of certain DNA sequences, such as AATC, to determine genetic variations.
