DNA Forensic Analysis Biotechnology

DNA is packaged in 23 chromosomes

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

Short repetitive sections of DNA STRs (short tandem repeats)

Variable Number of Tandem Repeats

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

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