1 Wednesday: Thursday: Experiments: 1: DNA-fingerprinting
2: Extraction of DNA 3: Microbiology: Assaying bacteria in our environment Thursday: Results from: 2: Microbiology: Assaying bacteria in our environment 4: Microbiology: Growth Factors and yeast 5: Blood: Testing for blood types

2 Location: Aalborghus Gymnasium, teachers’ preparation room
Crime Scene Report Location: Aalborghus Gymnasium, teachers’ preparation room Date: January the 31th, 07:30 AM

3 Primary suspects Suspect 1: Ole Suspect 3: Rolf Suspect 2: Thorbjørn
Suspect 4: Torben

4

5 Chromosomes and DNA

6

7 Variations i DNA SNP’s: Small Nuclear Polymorphisms
STR’s: Small Tandem Repeats STR’s gives the opportunity to separate them by size

8 A person inherit a copy (allele) of a STR region from each of the parents HOMOZYGOTE: both alleles are of the same length (same number of repeats) HETEROZYGOTE: the alleles are of different length (unevenly number og repeats)

9 CODIS (FBI 1997) Combined DNA Index System

10 Procedure Get your samples (handed out to you)
Extract DNA (already extracted) PCR: Multiply STR’s Gel Electrophoresis: Separate STR’s Stain DNA View results –Compare suspects with Crime Scene DNA
