What is the major histocompatibility complex (MHC)?
A)The major histocompatibility complex is a collection of circulating proteins that bind pathogens and enhance phagocytosis.
B)The major histocompatibility complex is a cell membrane barrier that blocks pathogens from entering cells if the MHC barrier is expressed.
C)The major histocompatibility complex is the term for the coordinated antibody-mediated response to a pathogen.
D)The major histocompatibility complex is a portion of chromosome 12 that contains genes that control the production of anti-viral proteins by normal cells.
E)The major histocompatibility complex is a portion of chromosome 6 that contains genes that control the synthesis of membrane glycoproteins.

Question

Quizplus · Accepted Answer

The major histocompatibility complex (MHC) is a portion of chromosome 6 in humans that contains genes that control the synthesis of membrane glycoproteins. These glycoproteins are expressed on the cell surface and are responsible for presenting antigens to T lymphocytes, which is a crucial step in the immune response. Therefore, the MHC plays a key role in recognizing self from non-self and initiating an immune response against pathogens.
