Answer:
Antibodies are made up of light chain and heavy chains. Heavy chain contains one variable region and three constant region while light chain have only one variable region and one constant region.
The variable region of the light chain and heavy chain of the antibody together makes the antigen-binding site called paratope which binds to their target antigen by non-covalent bond.
Epitope is the portion of an antigen that is recognized by the antibody and then the antibody binds to the epitope of antigen through its paratope region and helps in the killing of antigen.
Answer:cells that do not become reproductive cells.
Explanation: "SOMA' means BODY.
Thus,Somatic cells are body cells.They are all cells of the body except non reproductive cells.
They are multiplied by mitosis.

The nucleus is enclosed by a double layered cellular membrane called the nuclear membrane.
<h2>Nucleoplasm</h2>
The nucleus contains a nuclear sap, enclosed by the nuclear envelope, which is known as the nucleoplasm. This holds the nucleoli and suspends the chromatins.
<h2>Nucleolus</h2>
The nucleolus is a sub-organelle present inside the nucleus. It can be observed as a dark spot under the microscope.
Nucleoli are made up of proteins, ribosomal RNA (rRNA), and ribosomal DNA (rDNA).
<h2>Chromatin network</h2>
DNA gets associated with protein molecules to form chromatins.
Chromatins are present in the nucleoplasm.
