Biology Quote by Siddhartha Mukherjee
““It is dynamic. In some cells, it reshuffles its own sequence to make novel variants of itself. Cells of the immune system secrete "anti-bodies"-missilelike proteins designed to attach themselves to invading pathogens. But since pathogens are constantly evolving, antibodies must also be capable of changing; an evolving pathogen demands an evolving host. The genome accomplishes this counter-evolution by reshuffling its genetic elements-thereby achieving astounding diversity)s...tru...c...t...ure and g...en...ome can be reshuffled to form an entirely new word c...ome...t). The reshuffled genes generate the diversity of antibodies. In these cells, every genome is capable of giving rise to an entirely different genome.””

The immune system creates antibody diversity by rearranging genetic segments, enabling adaptation to evolving pathogens.
In simple terms: Immune cells remix DNA to make many antibodies.
