Telophase. Thaum lub sij hawm telophase, cov chromosomes pib uncoil thiab tsim chromatin. Qhov no npaj cov khoom siv caj ces los tswj cov kev ua haujlwm metabolic ntawm cov hlwb tshiab.
Chromosomes uncoil ua dab tsi?
Tam sim no tias cov chromosomes tau sib cais, ob lub nuclei raug tsim. Cov spindle fibers ploj; cov chromosomes uncoil thiab dhau los ua spaghetti-zoo li chromatindua, thiab cov membrane nuclear rov tshwm sim. Cytokinesis yog qhov chaw cytoplasm faib ua ob lub hlwb thiab feem ntau tshwm sim ib txhij nrog telophase.
nws hu li cas thaum chromosomes hloov mus ua chromatin?
Chromatin condensation pib thaum prophase (2) thiab chromosomes pom.

theem twg ua chromosomes Decondense rau hauv chromatin?
Thaum telophase ob pawg chromatids yog ib puag ncig los ntawm cov ntaub so ntswg tshiab thiab chromosomes decondense rau hauv chromatin. Cytokinesis (kev faib cov cytoplasm rau hauv ob lub hlwb) ua raws li telophase.
YPob chromosomes uncoil hauv meiosis?
Meiosis pib nrog Meiosis I. Thawj theem hauv Meiosis kuv yog prophase I. Thaum lub sij hawm no, DNA condenses rau hauv chromosomes. … Ntawm no cov spindle fibers tau tawg, cov ntaub ntawv tshiab nuclear tsim, chromosomes uncoil, thiab cell faib ua ob tug ntxhais hlwb.
