Text Solution

Verified by Experts

The correct Answer is:
B
Oparin reported that if a mixture of a large protein and a polysaccharides is shaken, coacervates are formed. The core of these coacervates was mainly formed of protein, polysaccharides and some water and was partially isolated from the surrounding aqueous solution having lower amount of proteins and polysaccharides. Coacervates could grow by absorbing materials from outside and could increase in number by budding.
