But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

3| Separate the fragments of DNA by electrophoresis through an agarose gel (for example, a 0.7% gel cast in 0.5× TBE or 1× TAE buffer). Maintain a low voltage through the gel (≤1 V/cm).

Specifically, the detection of DNA sequence variations plays an important role in the diagnosis of genetic-related diseases and conditions, especially for early stage treatment and monitoring.
