Using genes to unlock the secrets of Tutankhamen

Tutankhamen was an Egyptian pharaoh who ascended to the throne in 1333 BC, at the age or nine or ten. His fame in modern times is due to the discovery of his virtually intact tomb in 1922. Since then, many questions have been asked about his life and ancestry. Listen to this audio clip to find out how genetic technology ...

Inheritance, cell division and DNA duplication

What do you know about cell division? Look at images of a cell dividing, taken through an electron microscope. Discover a type of cell division called mitosis that is an important part of growth and repair in multicellular organisms. Compare that to the way cells divide through sexual reproduction in a process called meiosis. ...

Gene therapy: two sides of a coin

Learn about the two types of gene therapy: somatic and germline. Explore how somatic gene therapy has made giant strides towards developing treatments for some human diseases and disorders. Consider the ethical issues surrounding germline therapy, by which genetic changes would be passed on to later generations.

Selecting and synthesing genes

Discover how scientists can isolate and construct genes. See how they can make different types of DNA libraries to screen for a particular genes, and learn how genes can be completely re-created (synthesised) once their DNA sequence is known. Explore the range of recombinant DNA and genetic engineering techniques used to ...

Genetically modified food: divided perspectives

Imagine that farmers were able to droughtproof or pest-proof their crops. Manipulating genes in food can provide solutions to many farming and food supply problems. However, not everyone agrees on how this new technology should be used. Watch this clip to find out why some Australian farmers are divided on this issue.
