Question

How many polypeptide chains are present in gamma immunoglobulin?

• A. 5
• B. 4
• C. 6
• D. 2

Answer 1

The correct option is B 4

Antibodies are immunoglobulins or gamma globulins that are large, Y-shaped proteins, produced by plasma cells that are used by the immune system to identify and neutralize pathogens, like bacteria and virus. These are produced in response to the antigen. Antibodies typically have 4 chains, two large heavy chains, and two small light chains.

So, the correct answer is '4'.
