What else can I help you with?
Which genotype will give rise to the Bombay phenotype?
The Bombay phenotype is caused by a homozygous recessive mutation in the FUT1 gene, which results in the absence of H antigen on red blood cells. Therefore, the genotype for the Bombay phenotype is hh.
What type contains neither antigen a and b?
O
What is a monovalent antigen?
A monovalent antigen is a type of antigen that contains only one type of epitope, which is the specific molecular structure that can be recognized by the immune system. This means that the antigen can only trigger a response from one type of antibody.
What area is antigen challenge and clonal selection most likely to occur?
Antigen challenge and clonal selection are most likely to occur in the secondary lymphoid organs, such as the lymph nodes and spleen. These organs are where antigens encounter immune cells, triggering an immune response and the selection of specific immune cell clones.
What nonlymphocyte cell is a central actor in clonal selection?
Antigen-presenting cells (APCs) are nonlymphocyte cells that play a central role in clonal selection. They present antigens to T cells, triggering the immune response and selection of specific clones of T cells that can recognize and respond to the antigen.
What happens if your HIV sample contains the disease antigen?
whats the treatment for hiv/aids?
What is clonal selection responsible for?
Clonal selection is responsible for the production of a large population of identical B or T cells that specifically recognize and target a particular antigen. This process is critical for the adaptive immune system's ability to mount a targeted immune response against pathogens.
Is B a human blood phenotype?
No, B is a blood type representing the presence of the B antigen on red blood cells. It is one of the ABO blood group system classifications.
Blood type that contains A agglutinogens?
Type A, is this from the Blood Basics Quiz? I hate that thing.
Alloreactivity is a positive selection step or negative selection step?
Neither. Alloreactivity has to do with a lymphocytes reacting to a foreign antigen. Positive and negative selection are processes of central tolerance which is to say that they deal with a T cell's ability to bind self-antigen.
In clonal selection of b cells which substance is responsible for determining which cells will eventually become cloned?
there are 100,000 antibodies on the surface of b-cells which are specific for particular type of antigen therefore if specific antibody recognize the particular type antigen then it attach with it and activated.
What is the molecule that can be recognized by the immune system?
Antigens.
