Problem:
Which of the following is FALSE pertaining to antigen affinity in the adaptive immune system? Group of answer choices B lymphocytes are both produced and mature in the bone marrow, whereas T lymphocytes are produced in the bone marrow but mature in the thymus. B lymphocytes which are produce a large amount of a specific immunoglobulin are known as plasma cells. Both T cell receptors and immunoglobulins undergo extensive genetic and biochemical processing. The T cell receptor typically correlates with either CD4, which binds to MHC Class I antigens, or CD8, which binds to MHC Class II antigens. Whereas antibodies are capable of binding to extracellular antigens without the need for processing, T cell receptors are only capable of binding to peptide-based pathogens which have been processed by antigen-presenting cells.
