Question

Monoclonal antibodies and polyclonal antibodies are produced by

• A. T-memory cells
• B. NK -cells
• C. Plasma cells of B-lymphocytes
• D. Memory cells of B-lymphocytes

Answer 1

The correct option is C Plasma cells of B-lymphocytes

Antibodies are produced by plasma cells of B-lymphocytes. Monoclonal antibodies are particularly produced by plasma cells when combined with myeloma cells on a specific medium. These cells play a key role in specific immunological reactions.
T- and B- memory cells can recognize an antigen a long time after the original exposure.
NK or natural killer cells kill virus-infected cells and tumour cells by creating pores in the plasma membrane of the target cells.
