This flash animation shows the processes involved in the Sanger sequencing method – the DNA sequencing method used during the Human Genome Project.
This animation shows the principles and techniques involved in the Sanger, or chain-termination, method of DNA sequencing.
Developed in 1977 by Fred Sanger, the Sanger sequencing method enables scientists to read the genetic code of DNA. It is based on the natural process of DNA replication where new strands of DNA are synthesised using an existing strand as a template. A mixture of labelled and unlabelled nucleotides are added and the DNA sequence is read by a machine.
