  1. DNA Forensic Analysis Biotechnology

  2. DNA is packaged in 23 chromosomes

  3. Humans have small DNA differences we call • Polymorphisms- • Smaller polymorphisms are called SNPs. • Single nucleotide polymorphisms

  4. Short repetitive sections of DNA • STRs (short tandem repeats)

  5. Variable Number of Tandem Repeats

  6. Restriction Fragment Length Polymorphism (RLFP) • Digest DNA with restriction enzymes and separate using gel electrophoresis
