Answer:
The correct answer is option - D. phosphorylation.
Explanation:
The CARD11 or caspase recruitment domain-containing protein 11 is a gene that provides instructions for gene expressing to make a protein in the function of lymphocytes in the immune system. Lymphocytes like B and T cells are activated with the help of cascade reactions in which these genes provide information.
The protein that activates is PKC which is a kinase enzyme that implicates that the process that activates CARD11 is phosphorylation.
Thus, the correct answer is option - d - phosphorylation.
