Question

Describe gel electrophoresis technique in brief.

Hint:

Gel electrophoresis = Separates biomolecules by size using an electric field, smaller fragments move faster.

Answer 1

Gel electrophoresis is a technique used to separate DNA, RNA, or proteins based on their size and charge.In this technique, samples are loaded into wells of an agarose or polyacrylamide gel and subjected to an electric field. DNA fragments migrate towards the positive electrode, with smaller fragments moving faster. This helps in analyzing genetic material for research or forensic purposes.
