These animations, from the Wellcome Trust, explore DNA structure, function and analysis. They explain the biological processes that transcribe and translate the genetic code to produce proteins. Animations also illustrate how the processes used to sequence DNA have developed to allow genomes to be analysed at a...

A Catalyst article about Dolly the sheep which was born in 1996. The scientists who created her claimed she was a ‘clone’ from a female adult sheep. To prove this claim, genetic profiling or fingerprinting was done by another, independent group of scientists. The article explores how this was done and what other...

Produced by the Wellcome Trust Sanger Institute, this resource contains an overview of the techniques involved in making a BAC (Bacterial Artificial Chromosome) library. It consists of an animation that covers the key stages in the process:

From the Wellcome Trust Sanger Institute, this animation shows a detailed overview of the processes involved in the dideoxy or Sanger method for sequencing DNA. This is the method used to sequence the human genome. The animation demonstrates the principles and techniques involved in the Sanger sequencing method,...

Activities in this resource aim to:

• celebrate the achievement of completing the Human Genome project in 2003
• show the relevance of genome sequencing today
• explain the methods used for DNA sequencing, including the illumina method of rapid sequencing and the shotgun sequencing

A collection of resources about DNA replication.  These resources are part of the post 16 genetics and genomics collection.

Diagramatic representation of the replication of DNA. This is the process by which the cell makes a copy of its existing DNA before it divides. This therefore ensures that each new cell receives a full complement of DNA. The DNA polymerase enzyme can only add new bases in the 5'-3' direction. This leads to...

In this method, the DNA is used as a template to generate a set of fragments that differ in length from each other by a single base. The fragments are then...

This animation, from the Wellcome Trust, illustrates how the DNA code is used to build protein molecules inside our cells.

It shows how, during the process of transcription, polymerase unzips the DNA and uses it as a...

A collection of resources covering DNA, genes and chromosomes. This collection is part of the Post 16 genetics and genomics collection.

A Catalyst article about the work of Damian Murphy a music technologist. Acoustics and sound are examined in addition to the physical modelling and acoustics of buildings and environments, both real and virtual.

This article is from Catalyst: GCSE Science Review 2007, Volume 17, Issue 3.

This Mathematics Matters case study, from the Institute of Mathematics and its Applications, looks at how mathematical models try to understand the causes of rogue waves. These huge waves appear without warning, towering high over ships and oil rigs. Traditional mathematical models could not predict the occurrence...

Published by the Wellcome Trust in January 2011, this report provides the findings from the final stage of the evaluation of the Darwin Education Initiative. It includes the findings from follow-up interviews with case study schools which explored the continued use of the Great Plant Hunt and Survival Rivals...
