- What is DNA composed of? Nucleotides are chemical building units that makeup DNA.
- A phosphate group, a sugar group, and one of four different nitrogen bases make up these building components.

Nucleic acids include DNA and ribonucleic acid.
- Short tandem repeats (STRs) and variable number of tandem repeats (VNTRs) are the DNA sequence types most frequently employed in forensics and to identify victims of natural disasters.
