C)C region receptors
D)recombination signal receptors

Question

Quizplus · Accepted Answer

Jawless fish, such as lampreys and hagfish, lack the typical immunoglobulin-based adaptive immune system found in jawed vertebrates. Instead, they utilize variable lymphocyte receptors (VLRs) to recognize and respond to antigens. These VLRs are diverse and can generate a wide range of antigen receptors, providing a unique adaptive immune mechanism in these ancient vertebrates.
