Q. Assertion (A) The ADA gene provides instruction for producing the enzyme adenosine deaminase.
Reason (R) This enzyme is found throughout the body but is most active in lymphocytes.

Biotechnology and its Applications

Solution:

Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion. The ADA gene provides instructions for producing the enzyme adenosine deaminase. This enzyme is produced in all cells, but the highest levels of adenosine deaminase occur in the immune system cells called the lymphocytes, which develop in lymphoid tissues. Lymphocytes are a part of the immune system, which defend the body against potentially harmful invaders, such as viruses or bacteria.
