Question

The two protoplasts are fused with a fusogen called as

• A. Polyethylene glycol
• B. Ployvinyl chloride
• C. Polyethane glycol
• D. Phosphoric ethane

Answer 1

Answer: (A)

Polyethylene glycol

• The process by which protoplasts of two cells of different plants are fused to form hybrid is known as somatic hybridization.
• In this process, the protoplasts are fused using the agent polyethylene glycol. This agent along with calcium ions and sodium ions causes the development of charges on the surface of the cell membrane.
• This results in the packaging of the protoplasts in the cell membrane due to the activities of the ions with the cytoplasmic proteins.

Thus, the correct answer is option A.
