1.	At which stage of HIV infection does one usually show symtomas of AIDSA. Within 15 days of sexual contact with an infected personB. When the infected retro virus enters host cellsC. When HIV damages large number of helper T-lymphocytesD. When the viral DNA is produced by reverse transcnptase
Answer» Correct Answer - C T-lymphocyte receptors can recognise only antigen that bound to cell membrane proteins. These lymphocytes mediate CMI (cell mediated immunity). B-lymphocytes are the major effector molecules of humeral immunity. Erythrocytes are red blood cells. Thrombocytes or platelets secrete factors, that are involved in vascular repair.
