Nws yog lub sijhawm interphase, telophase, thiab cytokinesis uas cov chromosomes tsis pom lawm.
theem twg yog chromosomes tsis pom?
Nyob rau hauv interphase, tus neeg chromosomes tsis pom, thiab chromatin zoo nkaus li diffuse thiab unorganized.
Lub sijhawm twg ntawm lub voj voog ntawm tes yog chromosomes tsis pom?
No, chromosomes tsis pom thaum lub sij hawm the Interphase ntawm cell cycle bcoz ntawm ntau cov dej hauv cov nucleus. Raws li cov ntsiab lus dej ntau dua hauv cov nucleus. lawv tshwm zoo li cov xov zoo li cov qauv hu ua chromatin, uas condenses (Xoos dej) los ua cov qauv compact hu ua chromosomes.
Puas chromosomes tsis pom thaum lub sij hawm interphase?
Thaum lub sijhawm interphase (1), chromatin yog nyob rau hauv nws qhov tsawg kawg nkaus condensed lub xeev thiab zoo li xoob faib thoob plaws hauv lub nucleus. Chromatin condensation pib thaum lub sij hawm prophase (2) thiab chromosomes pom. Chromosomes tseem condensed thoob plaws hauv ntau theem ntawm mitosis (2-5).
Lub sijhawm twg ntawm chromosome disperse tsis pom lawm?
Telophase. Cov membranes tshiab tsim nyob ib ncig ntawm tus ntxhais nuclei thaum lub chromosomes tawg thiab tsis pom nyob rau hauv lub teeb lub teeb. Cytokinesis lossis kev faib tawm ntawm tes kuj tseem yuav pib thaum lub sijhawm no.
