O They have many different opitopes, which each bind to specific antibodies O They have two eptopes per cell O They are not antigenic. O They have one identfiable antigen that binds antibody. O They have many different epitopes, which all bind to the same antibody 6 An individual antibody is made against O O O one epitope of an antigen a whole bacterial cell one antigen on the cell the cell's DNA al of the combined antigenic determinants on a cell 7. Many different antibodies can be made against a single antigen True False

Explanation / Answer

4. They can contain many different antigenic determinants (epitopes)

an antigen can have multiple different epitopes, a number of antibodies can bind to a single antigen.

5.They have many different epitopes, which each bind to specific antibodies
