Agarose extracted from sea weeds finds use in

Options

  1. Atissue culture
  2. BPCR
  3. Cgel electrophoresis
  4. Dspectrophotometry

Correct answer

C. gel electrophoresis

Step-by-step solution

Gel electrophoresis is a technique to separate fragments of DNA. Since DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix. Now-a-days the most commonly used matrix is agarose which is a natural polymer extracted from seaweeds ( e g , Gelidium, Gracilaria, Gigartina, etc.).
