Question

Using PCR (Polymerase Chain Reaction) to amplify the same region of the genome from different individuals can identify differing lengths due to different numbers of repeated sequences referred to as:

Answer 1

PCR can identify differing lengths of repeated sequences, known as short tandem repeats (STRs), when amplifying the same region of the genome from different individuals.

Step-by-step explanation:

The process of using PCR (Polymerase Chain Reaction) to amplify the same region of the genome from different individuals can identify differing lengths due to different numbers of repeated sequences. These repeated sequences are referred to as short tandem repeats (STRs). STRs are regions of the genome that have a variable number of repeating DNA sequences. By amplifying these regions using PCR and comparing the lengths of the repeated sequences, scientists can differentiate individuals based on their unique DNA profiles.
