Explanation / Answer
A. Which statement regarding antibody structure is most FALSE?
a.Antibodies possess a constant region which is characteristic of the species generating the antibody.
b.Antibodies possess a variable region which specifically binds a particular antigen.
c.Antibodies bind to epitopes on antigens
d.Antibodies are present in the red blood cells of organisms with developed immune systems (like mammals).
ANSWER:
The Options a, b and c are the correct ones
But Option d which says Antibodies are present in the RBCs of organisms in incorrect.
Antibodies are present in the Plasma of the Blood. Not in the RBCs, infact RBCs are present in the Plasma of blood.
B. A secondary antibody binds to the primary antibody in an ELISA test.
ANSWER:
In ELISA, one of the type is Indirect ELISA, in which a plate is coated with the antigen and a primary antibody binds to the antigen. A secondary antibody is added that binds to the first antibody. The 2nd antibody contains the enzyme that reacts with the substrate
As the given statement is true.Hence, Option a is correct.
