Which of the following classes of cell surface receptors are directly encoded in the germ line?

Question

Quizplus · Accepted Answer

Pattern Recognition Receptors (PRRs) are directly encoded in the germ line, allowing for a consistent and immediate response to common pathogen-associated molecular patterns (PAMPs) without the need for prior exposure or somatic recombination. TCRs (T-cell receptors), BCRs (B-cell receptors), and antibodies undergo somatic recombination to increase diversity, and thus are not directly encoded in the germ line.
