Try sequencing DNA yourself

This animation shows you the basic steps in the Sanger method of DNA sequencingDNA sequencing
DNA sequencing is the process of working out the precise sequence of nucleotides within a strand of DNA.
. The Sanger method, used in the original Human Genomehuman genome
The complete sequence of all 20,000-25,000 human genes. That is, which chromosomes they are in and whereabouts the gene appears on that chromosome's piece of DNA.
Project, provides the foundation on which all modern sequencing methods have been built. Although next-generation and third-generation sequencing are much more complex processes, the basic principles remain the same.

This animation has five sections. The animation will stop at the end of each section.

Click on the grey arrow to start the animation running. The animation can be stopped and restarted at any point. A section can also be viewed again.

The red arrows that appear on the left after section one will return you to the very beginning of the animation.
