b.

Agarose is a polysaccharide obtained from fungus

c.

It is composed of glucose residues

d.

It is obtained via dissolving in its water by boiling in water and then cooling it

Discuss
Answer: (a).Agarose is a polysaccharide which is obtained from red algae
Q12.
Polyacrylamide gels are the other types of gels which are commonly used. Which of the following statement is not correct with respect to these types of gels?
