Study Notes
Forensic Science Activities
- The main focus of Activity 1.3: The Traces We Leave Behind is on the traces of evidence left behind at a crime scene.
Blood Typing
- Activity 1.2: Reliable Witnesses involves determining blood types using agglutination testing.
- Agglutination testing is a technique used to determine a person's blood type by observing clumping of blood.
DNA Composition
- DNA nucleotides are composed of a sugar molecule, a phosphate group, and a nitrogenous base.
DNA Analysis
