Which of the following statements are true about antibodies? A. Polyclonal antibodies are part of the natural immune response; monoclonal antibodies are clones of plasma cells used for medical research.
B. Polyclonal antibodies are used for the treatment of cancer; monoclonal antibodies are used for medical research.
C. Monoclonal antibodies work against many types of antigens; polyclonal antibodies work against a specific antigen.
D. Both Polyclonal and Monoclonal antibodies are naturally produced in immune responses.

The answer are A and D.

Explanation:

ANTIBODIES

Antibodies are immunoglobulin produced in the body by B cells to help i

For immune response or fight against any foreign invade in the body.

There are two common classification of antibodies and these are;

1. Monoclonal antibodies are produced in the laboratory that can help to restore and improve the immune system against cancer attack.

They bind to the antigens and are many on the surface of cancerous cells than normal cells. They are use for medical research.

2. POLYCLONAL ANTIBODIES are produced by different B cells the body. They are produced from heterogeneous molecules in live animals. They can bind to numerous antigens. They are part of the natural immune response of the animals. They are produced by injecting the animal with immunogen.

Therefore, Polyclonal antibodies are part of the natural immune response; monoclonal antibodies are clones of plasma cells used for medical research.

Both Polyclonal and Monoclonal antibodies are naturally produced in immune responses
