11 slides on DNA fingerprinting. Great for a high school forensics class. Goes into PCR technique. Here is an excerpt:
DNA – Deoxyribonucleic Acid – polymer found in almost all living cells.
Discovered in 1868
Structure discovered in 1950’s by Watson and Crick (double helix).
46 chromosomes ? 100,000 genes ? 3 billion base pairs
DNA base pairs ? amino acids ? proteins
Genes can be 1,000 base pairs or as long as several hundred thousand base pairs
