The T-lymphocytes mediate the cell mediated immunity (CMI). T-cells respond to antigens by producing a clone of T-cells. Each T-cells recognise a specific antigen. The clones of T-cells, produced to respond an antigen are similar but they perform different functions, they are Killer T-cells (KT-cells), Helper T-cells (HT-cells), Suppressor T-cells ( ST-cells).

An immunoglobulin \(G\) molecule is composed of :
1 Two different heavy chains and two identical light chains
2 Two identical heavy chains and two different light chains
3 Two identical heavy chains and two identical light chains
4 Two different heavy chains and two different light chains
Explanation:

Identify the bond depicting ' X ' in the following diagram.
1 Hydrogen bond
2 Disulphide bond
3 Ester bond
4 Glycosidic bond
Explanation:
Each H-chain has disulfide linkages (-S-S-). L-chains are covalently linked with \(\mathrm{H}\)-chains by disulfide bridge (-S-S-).

Which is wrong?
1 Body's first line of defense is skin
2 Second line of defense is skin and phagocytic cells
3 Third line of defense is immune system
4 Lines of body defense are skin, phagocytic cells and immune system
Explanation:
Second line of body defense is only Phagocytic cells which ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes (a type of white blood cell).

An antibody molecule is represented as
1 \(\mathrm{H}_{2} \mathrm{~L}_{2}\)
2 \(\mathrm{H}_{3} \mathrm{~L}_{2}\)
3 \(\mathrm{H}_{2} \mathrm{~L}_{3}\)
4 \(\mathrm{H}_{4} \mathrm{~L}_{4}\)
Explanation:
Antibody is represented as \(\mathrm{H}_{2} \mathrm{~L}_{2}\) because it has two heavy chain \(\left(\mathrm{H}_{2}\right)\) and two light chain \(\left(\mathrm{L}_{2}\right)\). It has a y shaped structure.

The function of helper T-cell is to
1 Kill the antigen
2 Kill the antibodies
3 Suppress B-cells
4 Stimulate B-cells
