A double helix DNA shown as a double twisted string with interlinking parts. Base pairs on a DNA molecule. Each strand of DNA is made of chemicals called bases. There are four different types of bases. In DNA, two strands coil together to form a double helix. There are chemical cross-links between the two strands,...

With a few clicks and some spit you can now buy a reading of your DNA online. You can find out where you came from, trace relatives around the world and find out about your predisposition to disease and which sports you might be most suited to. In this book, journalist and DNA scientist Sergio Pistoi investigates...

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...

The place of DNA in the story of life and evolution is presented here and explained by means of models to cut out and glue together. There are also other models which shed light on nucleotides, viruses and protein...

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.

James Watson, the co-discoverer of the structure of DNA and author of the international bestseller 'The double helix', tells the story of the amazing molecule since its discovery fifty years ago, following modern...

This item is one of over 25,000 physical resources available from the Resources Collection. The Archive Collection covers over 50 years of curriculum development in the STEM subjects. The Contemporary Collection includes all the latest publications from UK educational publishers.

This book and accompanying teacher guide focus on the story of a young girl and her passion for saving water. The story follows the journey of an ordinary schoolgirl in the UK, who transforms into a water superhero when a DRY summer is followed by a DRY winter. The teacher guide provides eight linked activities...

The activities are based on science and technology but don t require any particular technical, DIY or science abilities. None of it is rocket science (actually, a bit of it is!). All the activities and experiments...

Ten plastic boxes that nest together to form a compact cube but can then be slotted together to form...
