PATHOLOGY

Detailed explanation-1: -Antibodies are produced by B cells (specialized white blood cells). When an antigen comes into contact with a B cell, it causes the B cell to divide and clone. These cloned B cells-or plasma cells-release millions of antibodies into your bloodstream and lymph system.

Detailed explanation-2: -The antigen-recognition molecules of B cells are the immunoglobulins, or Ig. These proteins are produced by B cells in a vast range of antigen specificities, each B cell producing immunoglobulin of a single specificity (see Sections 1-8 to 1-10).

Detailed explanation-3: -Synthesized exclusively by B cells, antibodies are produced in billions of forms, each with a different amino acid sequence and a different antigen-binding site.

Detailed explanation-4: -The process is called somatic hypermutation, which allows B cells to mutate the genes that they use to produce antibodies. This stunning process allows B cells to produce antibodies that keenly bind to SARS-CoV-2-or any other virus or bacterial species that invades the body.
