Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Adenosine deaminase (ADA): Severe combined immunodeficiency (SCID) is a genetic disorder caused by the deficiency of the enzyme adenosine deaminase (ADA). This enzyme is essential for the normal development and function of the immune system, especially T and B lymphocytes. Its absence causes the buildup of toxic metabolites that damage these cells and the immune response is diminished.
Adenosine diphosphate: ADP is a nucleotide involved in cellular processes.
Adenosine cyclase: This is an enzyme that is involved in cyclic AMP formation.
Guanidine nitrate: This is a compound that has no connection with SCID.
