Question

Name the natural source of agarose mention one role of agarose in biotechnology

Answer 1

agarose is a polysaccharide generally extracted from certain red seaweeds ( plants grow naturally in sea without involvement of human)
in biotechnology it is used for gel electrophoresis by converting powder form of agarose to gel

Answer 2

Agarose is obtained from red seaweed.

Role of agarose in biotechnology is as base gel for the process of electrophoresis.

•Agarose is obtained from red seaweed or red algae.

•These are eukaryotic organisms.

•They are named so due to their red colour.

•Their red colour is due to presence of phycobiliproteins.

•Agarose is a polysaccharide, i.e made up by combination of many monomeric units.

•Agarose is made from agar by removal of agaropectin.

•Thus, agarose is purified form of agar.

•It is made of D-galactose and 3,6-anhydro-L-galactopyranose.

•Agarose is used in biotechnology in molecular biology field.

•Applications of agarose are in - restriction enzyme digestion, PCR.
