<prompt> Yikuphi ukucwaninga kwezinto eziphilayo okunesithakazelo kuma-antigen nakwezinye izinhlayiya ezingezona ezakho? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Kokubili amasosha omzimba angokwemvelo nawokuzivumelanisa nezimo kuncike ekhonweni lesimiso somzimba sokuzivikela ezifweni lokuhlukanisa phakathi kwamangqamuzana angawona awaso. Ku-immunology, ama-self molecule yilawo ma-component womzimba womuntu angahlukaniswa nezinto zangaphandle ngamasosha omzimba. Ngakolunye uhlangothi, ama-molecule angabonakali yilawo aqashelwa njengama-molecule angaphandle. Esinye isigaba sama-molecule angawona awomuntu siqu sibizwa ngokuthi ama-antigen isifinyezo sokuthi generators of antibody futhi sichazwa njengezinto ezibopha ama-receptor athile omzimba futhi zibangele ukusabela komzimba.
