Noma iluphi ushintsho oluhlala njalo ekulandeleni kwe-DNA olwenza isakhi sofuzo
Impendulo ithi: ukuguqulwa kwezakhi zofuzo.
Ukuguquka kwezakhi zofuzo kwenzeka lapho kunoshintsho oluhlala njalo ekulandeleni kwe-DNA okwakha isakhi sofuzo.
Lolu hlobo loshintsho lungase luholele ekwenyukeni noma ekwehleni kwenani lama-chromosome kuseli.
Okunye ukuguqulwa kwezakhi zofuzo kungaba yingozi futhi kuholele ekuzalweni okukhubazekile noma ezinye izinkinga zempilo, kodwa futhi kukhona ukuguqulwa okuhle okungaholela ezicini ezintsha kanye nezinguquko ezinhle zokuphila.
Nakuba ukuguqulwa kwezakhi zofuzo kungenakuvinjelwa ngokuphelele, ezinye izinyathelo zingathathwa ukuze kuvinjelwe izimbangela ezithile ezingagwemeka ezingaholela ezinguqukweni, njengokuchayeka kumakhemikhali ayingozi emiphakathini yezimayini neyezimboni.
