STRs
short tandem repeats
sections of a chromosome in which DNA sequences are repeated
DNA
Deoxyribonucleic acid the molecule of heredity, common to all life forms, that is passed from parents to offspring molecule of inheritance common to all life forms instruction for organism's structure located in the nucleus
