DNA can be used to tell people apart - their DNA sequences or the lengths of repeated regions of DNA
Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique.
- DNA contains genetic information that is passed from adult organisms to their offspring during reproduction.
- Each offspring forms by the combination of the parent's gene or DNA
- The actual sequence of DNA on each of the chromosomes is unique due in part to recombination.
- recombination causes genetic variation and made everyone unique.
- This is incorporated in the nucleotide sequences in DNA molecules.
Thus, DNA can be used to tell people apart - their DNA sequences or the lengths of repeated regions of DNA
