    Hybridoma is a bio-technique which involves fusion of

    A)  B-cells and T-cells           

    B)  T-cells and spleen cells

    C)  spleen cells and myeloma

    D)  myeloma cell and B-cells

    Correct Answer: D

    Solution :

                     A hybridoma is a hybrid cell obtained by fussing a B-lymphocyte with tumour cells of the antibody forming system or of B-lymphocytes (called myelomas). The hybrid cell thus produced possess the ability to produce antibodies due to the B-lymphocyte genome and the capacity for indefinite growth in vitro due to the tumour cells involved in the fusion. The technology was developed by G Kohler and C Milstein in 1975. T cells (T lymphocytes) are a population of lymphocytes that are the principal agents of cell mediated immunity. T-cells are derived from the bone marrow but migrate to the thymus to mature hence, are known as T cells.
