An Individual Antibody is Made Against

Question

An individual antibody is made against
A) a whole bacterial cell
B) one epitope on the cell
C) one antigen on the cell
D) all of the combined antigenic determinants on a cell
E) the cell's DNA

Accepted Answer

An individual antibody is made against one epitope on a bacterial cell or other antigen. An epitope is the specific part of an antigen that the antibody recognizes and binds to. Therefore, an individual antibody is made to recognize and bind to a specific epitope, not the entire bacterial cell, one antigen, all the combined antigenic determinants on a cell, or the cell's DNA.
