Isolation of DNA molecule
Separation of DNA fragments according to their size
Separation of DNA fragments according to their size
Solution
Gel electrophoresis is a widely used technique in molecular biology that allows the separation and analysis of DNA, RNA, and proteins based on their size and charge.
In the case of DNA, the technique involves placing the DNA samples onto a gel matrix, typically made of agarose or polyacrylamide, and applying an electric field across the gel.
The DNA fragments migrate through the gel based on their size and charge, with smaller fragments moving faster and traveling farther from the point of origin.
