Understanding DNA extraction

Discover how DNA is extracted and some applications of this technique by using this VIRTUAL LAB

Who's your Daddy? - Understanding Gel Electrophoresis

This VIRTUAL LAB shows you the technique used to seperate DNA fragment according to molecular size. The smaller the fragment the faster it moves through the gel. This has been used in DNA fingerprinting since the protocol was invented in 1975. It was commonly used in crime scene analysis and paternity testing. A second animation can be found here.

Understanding PCR

This is a great animation that allows you to perform PCR in a 'VIRTUAL LAB". You step through the process of Polymerase Chain Reaction (PCR) watching what happens at each step.

Biotechnology Learning Hub

This resource is excellent for finding out about what biotechnology is being used in New Zealand in areas of biocontrol, crime scene analysis, human health, and agriculture. Click here to read great STORIES. Watch animations and read more about techniques in the DNA LAB

DNA packaging

Watch the following video clip to show the relationship between the DNA molecule, histones, and when we can define it as Chromatin or a Chromosome.

Endosymbiosis - Evolution of Eukaryotic cells

The following video clip gives an overview of the process of endosymbiosis and the evolution of a more complex cell with double membrane bound organelles.

A tour of the cell - Bozeman Biology

We need to become familiar with the major organelles of the cell. This video clip steps through each organelle explaining function and structure. (Recap from 12 Biology)
