Question

Agarose is a polysaccharide, composed of:

• A. \( \text{D-galactose and agarobiose} \)
• B. \( \text{D-glucuronic acid and sulfated D-glucuronic acid} \)
• C. \( \text{D-glucuronic acid and glucosamine} \)
• D. \( \text{D-galactose and 3,6-anhydro-L-galactopyranose} \)

Hint:

Agarose gels provide an efficient medium for molecular separation in analytical biochemistry.

Answer 1

The Correct Option is D

Agarose, widely used in gel electrophoresis, consists of D-galactose and 3,6-anhydro-L-galactopyranose. Its gel-forming properties enable separation of biomolecules, including DNA, RNA, and proteins. Other options describe different polysaccharide compositions, not specific to agarose.
