Interphase yog lub sijhawm rau lub cell los npaj rau meiosis thiab ib feem ntawm qhov kev npaj no suav nrog kev nce ob npaug ntawm cov chromosomes hauv lub cell muaj. Qhov no ib feem ntawm interphase yog hu ua S theem, nrog rau S sawv rau synthesis. Txhua chromosome xaus nrog ib tus ntxaib zoo tib yam hu ua tus muam chromatids.

Ib yam li ntawd, tib neeg nug, dab tsi tshwm sim hauv interphase 1 ntawm meiosis?

Chromosomes pom, hla dhau tshwm sim, cov nucleolus ploj, cov meiotic spindle cov ntaub ntawv, thiab lub hnab ntawv nuclear ploj mus. Thaum pib ntawm prophase Kuv, cov chromosomes twb duplicated. Thaum prophase Kuv, lawv coil thiab ua luv luv thiab thicker thiab pom nyob rau hauv lub teeb microscope.

Tsis tas li ntawd, puas muaj meiosis muaj kev cuam tshuam? Interphase . Muaj ob theem lossis theem ntawm meiosis : meiosis kuv thiab meiosis II. Ua ntej ib tug faib cell nkag meiosis , nws undergoes lub sij hawm ntawm kev loj hlob hu ua interphase . Nyob rau theem no, lub cell nce hauv huab hwm coj hauv kev npaj rau kev faib cell.

Tom qab ntawd, lo lus nug yog, dab tsi tshwm sim loj tshwm sim thaum interphase hauv meiosis?

Piv txwv li, ua ntej yuav mob meiosis, lub xovtooj ntawm tes mus dhau lub sijhawm cuam tshuam uas nws loj hlob, rov ua dua nws cov chromosomes, thiab xyuas tag nrho nws cov tshuab kom paub meej tias nws npaj txhij los faib. Zoo li mitosis, meiosis kuj muaj cov theem sib txawv hu ua prophase, metaphase, anaphase , thiab telophase.

Yuav ua li cas tshwm sim nyob rau hauv txhua theem ntawm interphase?

Peb theem ntawm interphase npe G1, S, thiab G2. Thaum lub sij hawm interphase , lub cell loj hlob thiab cov nucleus DNA yog duplicated. Interphase yog ua raws li mitotic theem . Thaum cov mitotic theem , cov duplicated chromosomes yog segregated thiab faib mus rau hauv tus ntxhais nuclei.
