Hujayra tsikli, hujayraning hayotiy tsikli \u2014 hujayraning bo’linishidan so’ng yana bo’linguncha yoki o’lguncha o’tgan hayot davri. Bir hujayralilar Hujayra tsikli ularning hayot davriga to’g’ri keladi. To’xtovsiz bo’linadigan hujayralar Hujayra tsikli mitoz tsikliga to’g’ri kelib, ketma-ket almashinib turadigan 4 davr: postmitoz yoki sintez dan oldingi (o, inglizcha \u00a7go\\u \u2014 o’sish, yiriklashish), sintez (8, inglizcha 8umpe518 \u2014 sintez), metoda oldingi yoki sintezdan keyingi (S2) va mitoz (M) dan iborat. S: davrda transkripsiya sodir bo’ladi; sintezlangan oqsillar to’planadi; DNK sinteziga tayyorgarlik ko’riladi. 5 davrda DNK replikasiyalanadi, xromosomalar materiali 2 hissa ortadi. S2 davrda hujayralar bo’linishga tayyorlanadi; bo’linish dukini hosil qiladigan oqsillar sintezlanadi. Mitoz \u2014 Hujayra tsiklining yakuniy davri bo’lib, unda reduplikatsiyalangan xromosomalar hujayraning har xil qutblariga tarqaladi. Hujayra tsikli va uning davrlarining davomiyligi ko’payadigan hujayralarning xili, yoshi, organizmdagi gormonlar balansiga bog’liq. Vaqtga nisbatan S: va S2 davrlari o’zgaruvchan bo’ladi; tinim davrlari bo’lgan Hujayra tsikli ayniqsa uzoq davom etadi. Bunday hollarda O0 yoki tinim davri (inglizcha \u00a7ar \u2014 oraliq, interval) alohida ajratiladi. Agar tinim davri hisobga olinadigan bo’lsa, u holda Hujayra tsikli haftalab, hatto oylab davom etishi mumkin (masalan, jigar hujayralari). Neyronlarda Hujayra tsikli organizm umriga teng bo’ladi.<\/p>\n","protected":false},"excerpt":{"rendered":"
