Umfanekiso weMitotic

Iyini isibalo se-mitotic

Isibalo se-mitotic iseli elisenqubweni yokuhlukana ukuze lidale amaseli amasha amabili. Le nqubo ibizwa ngokuthi i-mitosis. Izazi zezifo ziyakwazi ukubona izibalo ze-mitotic lapho zibheka izicubu ngaphansi kwesibonakhulu. Izibalo ze-Mitotic zibonakala kalula ngoba izinto zofuzo ngaphakathi nucleus ishintsha umbala nokuma ngaphambi kokuba iseli lihlukane.

Izigaba ze-mitosis

Inqubo ye-mitosis ihlukaniswe ngezigaba (bheka isithombe esingezansi). Lezi zigaba zibizwa ngokuthi i-prophase, i-metaphase, i-anaphase, ne-telophase. Ngesikhathi se-prophase inani lezakhi zofuzo kuseli liphindaphinda kabili ukuze kube nokwanele amaseli amasha amabili. Ngesikhathi se-metaphase izakhi zofuzo ziba phakathi nendawo yeseli. Ngesikhathi se-anaphase amaseli aqala ukuhlukana abe amangqamuzana amabili futhi izakhi zofuzo zihlukaniswa ngesigamu ukuya engqamuzaneni entsha ngayinye. Ekugcineni, ku-telophase, kwakheka amaseli amasha amabili anezakhi zawo zofuzo ngaphakathi nucleus.

Ngokuvamile atholakala kuphi amaseli ahlukanisayo?

Amaseli ahlukanisayo atholakala kuzo zombili izicubu ezijwayelekile kanye nezicubu ezingajwayelekile ezifana nomdlavuza. Ngenxa yokuthi umdlavuza ukhula ngokushesha kakhulu kunezicubu ezivamile, ngokuvamile unamaseli amaningi ahlukanisayo. Ama-Mitose nawo akhona kwabaningi isasebenza izimo (ezingezona umdlavuza).

Umdlavuza onama-mitose amaningi ukhula ngokushesha, kodwa lokhu kungase futhi kusho ukuthi kulula kakhulu ukuthola ukwelashwa okufana nokwelashwa ngamakhemikhali okuqondise kumaseli ahlukanayo.
