Question

name the material used as matrix in gel electrophorosis and mention its role

Answer 1

Agarose gel is used in electrophoresis which is obtained from sea weeds(algae - class= Rhodophyceae).
ROLE---
During gelation, agarose polymers associate non-covalently and form a network of bundles whose pore sizes determine a gel's molecular sieving properties. The use of agarose gel electrophoresis revolutionized the separation of DNA. Prior to the adoption of agarose gels, DNA was primarily separated using sucrose density gradient centrifugation, which only provided an approximation of size.
