Lab 1: DNA Fingerprint Analysis

Your DNA makes you ‘YOU’. No two individuals have the same DNA unless they are identical twins, triplets etc. In this simulation you will be looking at the DNA fingerprints of frogs. You will use the DNA fingerprints to identify twin frogs and investigate the relationship between DNA fingerprints and frog traits.

Open the DNA Fingerprint Analysis Gizmo.

Problem

How can identical twins and physical characteristics be identified using DNA fingerprints?

Procedure

Follow each step in the “Exploration Guide” in the DNA fingerprint analysis gizmo.
