<span>Answer:
Think of DNA-there are only 4 bases, but different combinations give infinite possibilities.
And the same for amino acids and proteins.
Immunoglobulins work on a similar principle. Different VDJ segments are combined for the heavy chain of an antibody. Different VJ segments are combined for the light chain.

Random nucleotides may be added or removed between the gene segments.
There are also different combinations of light and heavy chains.
Antibodies can be any of the 5 isotypes: IgA, IgM, IgG, IgE, IgD.
