Question

After using PCR on the same region from two individuals, you notice that each person's DNA yielded pieces of different sizes. Which of the following is the most likely explanation

Answer 1

Variable number tandem repeats (VNTRs) were formed.

Step-by-step explanation:

This is a case where VNTRs were formed. Variable number tandem repeats (VNTRs), which are also called mini-satelites are one of the families of repetitive DNA sequence dispersed in the genome. There are short nucleotide sequence that are organized in tandem repeats which have variations in length depending on individuals.
