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

7 PCR with primers, Heats and cools DNA to make billions of copies
