A discussion of the problems caused by genetic engineering.

Professor Jeffreys will describe how DNA typing can be used to solve casework and will review the latest developments, including the creation of major national DNA databases that are proving extraordinarily effective in the fight against crime.

Alec Jeffreys presents the origins of DNA fingerprinting through to the latest developments and their social impact

Genetic Programming is an artifical intelligence technique based off of natural selection. A generation of programs is generated, then tested using a fitness function. After that successful programs are altered and replicated successively until a d....

A brief overview of genetically modified organisms and their effect on the global population.

The human genome sequence has been available for more than a decade, but its significance is still not fully understood. While most human genes have been identified, there is much to learn about the DNA signals that control them. This lecture describ....

Since its introduction as a biological marker, the Aequorea victoria Green Fluorescent Protein (GFP) has had a strong impact in biology, being used in an ever-increasing variety of ways. I will review a bit of the history of GFP and show how having ....

The accidental discovery of this wonderful tool has changed the face of biology.
