Web5 Mar 2024 · Some of these methods do not require knowledge of the complete sequence of the DNA molecule. Before the advent of rapid DNA sequencing, these methods were the only ones available to work with DNA, but they still form the basic arsenal of tools used by molecular geneticists to study the body’s responses to microbial and other diseases. WebThe art of determining the sequence of DNA is known as Sanger sequencing after its brilliant pioneer. This technique involves the separation of flourescent labeled DNA fragments according to their length on a polyacrilimide gel (PAGE). The base at the end of each fragment can then be visualized and identified by the dye with which it reacts.
