Question

Each B-lymphocyte is individually programmed to recognise how many distinct antigens?

Options

• All antigens present in the body

• A single, distinct antigen

• Two antigens simultaneously

• Multiple related antigens from the same pathogen family

Answer 1

B lymphocytes are individually programmed to recognise a single, distinct antigen. This specificity ensures that each B-cell responds only to its matching antigen, providing targeted immune defence.
