Qhov sib txawv tseem ceeb ntawm anaphase thiab telophase yog tias thaum lub sij hawm anaphase, cov viv ncaus chromatids cais tawm ntawm ib leeg thiab tsiv mus rau qhov kawg ntawm tes thaum lub sij hawm telophase, nuclear membranes hloov kho thiab nucleoli rov tshwm sim.

Eukaryotes muaj qhov loj thiab nyuaj genome piv rau prokaryotes. Yog li ntawd, lub xub ntiag ntawm lub voj voog ntawm tes zoo yog qhov tseem ceeb heev los tsim cov ntxhais tshiab. Lub voj voog ntawm tes tuaj yeem muab faib ua tsib theem xws li G1, S, G2, mitosis, thiab cytokinesis. G1 theem yog lub sijhawm ntev tshaj plaws thiab yog thawj theem kev loj hlob ntawm tes. S theem, ntawm qhov tod tes, yog theem uas cell synthesis ib tug replica ntawm genome G2 theem yog lub thib ob loj hlob theem thaum mitosis yog lub sij hawm nyob rau hauv uas nuclear faib yuav siv sij hawm qhov chaw thiab tsim tau ob tug tib tus ntxhais nuclei. Tsis tas li ntawd, cytokinesis yog kev faib tawm ntawm cytoplasm thiab tsim cov hlwb tshiab cais. Mitosis muaj ob peb theem raws li prophase, metaphase, anaphase, thiab telophase. Kev sib cais ntawm tus muam chromatids thiab tsim ntawm tus ntxhais nuclei tshwm sim thaum lub sij hawm anaphase thiab telophase feem.

Anaphase yog dab tsi?

Anaphase yog qhov luv tshaj plaws ntawm txhua theem ntawm mitosis. Txog rau qhov no, cohesion proteins tuav tus muam chromatids ntawm lub centromere. Thaum pib ntawm anaphase, centromeres sib cais, thiab ob tug muam chromatids pib sib cais los ntawm kev tshem tawm cov cohesion proteins ib txhij los ntawm tag nrho cov chromosomes. Tom qab ntawd microtubules rub txhua tus viv ncaus chromosomes sai sai rau ntawm cov ncej ntawm tes. Muaj ob lub zog - 'Anaphase A thiab Anaphase B' - thaum lub sij hawm anaphase.

Daim duab 01: Anaphase

Kinetochores raug rub mus rau tus ncej thaum 'Anaphase A' thaum cov ncej txav sib nrug ua rau cov hlwb elongated thaum 'Anaphase B'. Ob qho kev txav no tshwm sim ib txhij nrog kev pab ntawm microtubules.

Telophase yog dab tsi?

Telophase yog theem kawg ntawm mitosis thaum lub sijhawm hloov pauv ntawm tus ntxhais nuclei tshwm sim. Hauv telophase, spindle apparatus dissembles thiab chromosomes tsis txuas mus rau microtubules ntawm lub centromere. Cov chromosomes tam sim no pib uncoil mus rau hauv ib daim ntawv txuas ntxiv uas tso cai rau cov noob qhia. Nuclear membranes hloov kho thiab nucleoli rov tshwm sim thaum lub sij hawm telophase.

Daim duab 02: Telophase

Ntxiv mus, telophase yog qhov thim rov qab ntawm cov txheej txheem ntawm prophase, nqa lub cell rov qab mus rau qhov sib cuam tshuam.

Dab tsi zoo sib xws ntawm Anaphase thiab Telophase?

  • Anaphase thiab telophase yog ob theem ntawm mitosis thiab meiosis.
  • Anaphase yog ua raws li telophase.

Qhov txawv ntawm Anaphase thiab Telophase yog dab tsi?

Anaphase tshwm sim tom qab metaphase thaum telophase tshwm sim tom qab anaphase. Qhov sib txawv tseem ceeb ntawm anaphase thiab telophase yog cov viv ncaus chromatids sib cais los ntawm ib leeg thiab txav mus rau ob tus ncej ntawm tes thaum lub sij hawm anaphase thaum rov tsim cov ntxhais nuclei tshwm sim thaum lub sij hawm telophase. Tsis tas li ntawd, qhov sib txawv tseem ceeb ntawm anaphase thiab telophase yog lub sijhawm. Lub sijhawm ntawm anaphase yog luv dua li ntawm telophase.

Thaum pib ntawm anaphase, tsuas muaj ib pawg ntawm viv ncaus chromatids teem rau hauv nruab nrab kab ntawm tes. Nyob rau hauv sib piv, thaum pib ntawm telophase, muaj ob pawg ntawm cov muam chromatids ntawm tus ncej ntawm lub cell. Yog li, qhov no kuj yog qhov sib txawv ntawm anaphase thiab telophase. Ntxiv mus, qhov sib txawv ntxiv ntawm anaphase thiab telophase yog qhov spindle apparatus tam sim no ntawm anaphase, whereas nws ploj ntawm telophase.

Summary – Anaphase vs Telophase

Anaphase thiab telophase yog ob theem ntawm mitosis uas piav qhia txog kev faib hluav taws xob. Anaphase tshwm sim tom qab metaphase thaum telophase tshwm sim tom qab anaphase. Thaum lub sij hawm anaphase, tus muam chromatids sib cais los ntawm ib leeg thaum lub sij hawm telophase, nuclear membranes hloov kho thiab nucleoli rov tshwm sim. Ntxiv mus, anaphase txuas ntxiv rau lub sijhawm luv luv dua li telophase. Yog li, qhov no qhia txog qhov sib txawv ntawm anaphase thiab telophase.
