In contrast, the remainder of the antibody is relatively constant. It only occurs in a few variants, which define the antibody's class or isotype: IgA, IgD, IgE, IgG, or IgM. The constant region at the trunk of the antibody includes sites involved in interactions with other components of the immune system. Hypervariable region: In antibodies, hypervariable regions form the antigen-binding site and are found on both light and heavy chains. They also contribute to the specificity of each antibody. In a variable region, the 3 HV segments of each heavy or light chain fold together at the N-terminus to form an antigen binding pocket. The antibody is said to "match" the antigen in the sense that it can bind to it due to an adaptation in a antigen-binding fragment of the antibody.
If the shape of the epitope corresponds to the shape of the antigen-binding site, it can fit into the site—that is, be “recognized” by the antibody. Each type of antibody binds to one unique epitope, because of the unique antigen-binding site of an antibody. In a word, an antibody binds to a particular antigen specifically. Fig. 2 shows the structures of epitope and antibody, which will help you better understand the specificity of antigen-antibody interaction.
At the molecular level, an antigen is characterized by its ability to be “bound” at the antigen-binding site of an antibody. Antibodies tend to discriminate between the specific molecular structures presented on the surface of the antigen.

Antibodies are a family of glycoproteins that bind specifically to foreign molecules (antigens). The binding between antibodies and antigens has high specificity and affinity resulting from NEET questions & solutions with PDF and difficulty level In the first step, a primary unlabeled antibody to the antigen of interest is added.

The fragment antigen-binding (Fab fragment) is a region on an antibody that binds to antigens. It is composed of one constant and one variable domain of each of the heavy and the light chain. These domains shape the paratope — the antigen-binding site — at the amino terminal end of the monomer. Hypervariable region: In antibodies, hypervariable regions form the antigen-binding site and are found on both light and heavy chains. They also contribute to the specificity of each antibody. In a variable region, the 3 HV segments of each heavy or light chain fold together at the N-terminus to form an antigen binding pocket. An antibody structure consists of a Y-shaped molecule composed of 4 polypeptide subunits.The N-terminus of the heavy chains associates with one of the light chains and forms two antigen binding domains.

It is composed of the variable domain from each of the heavy and the light chain.
It is composed of the variable domain from each of the heavy and the light chain. Therefore, the correct answer is option C. Antigen binding site in an antibody is found between(a) two light chains(b) two heavy chains(c) one heavy and one light chain(d) either between two light chains or betweenone heavy and one light chain dependingupon the nature of antigen.
