Mitosis muaj plaub theem pib: prophase, metaphase, anaphase, thiab telophase. Cov theem no tshwm sim nyob rau hauv no nruj sequential xaj , thiab cytokinesis - cov txheej txheem ntawm kev faib cov ntsiab lus ntawm tes los ua ob lub hlwb tshiab - pib hauv anaphase lossis telophase.

Tsuas yog li ntawd, dab tsi yog qhov kev txiav txim ntawm theem rau mitosis?

Cov theem ntawm mob mitosis : prophase, metaphase, anaphase, telophase. Cytokinesis feem ntau sib tshooj nrog anaphase thiab / lossis telophase. Koj tuaj yeem nco txog xaj ntawm theem nrog lub npe nrov mnemonic: [Thov] Pee ntawm MAT.

Ib tug kuj yuav nug, qhov kev txiav txim ntawm metaphase yog dab tsi? Metaphase yog theem ntawm mob mitosis uas ua raws li prophase thiab prometaphase thiab ua ntej anaphase. Metaphase pib thaum tag nrho cov kinetochore microtubules tau txuas nrog tus muam chromatids 'centromeres thaum lub sijhawm prometaphase.

Yog li ntawd, dab tsi yog theem ntawm meiosis nyob rau hauv kev txiav txim?

Yog li, meiosis suav nrog theem ntawm meiosis I ( prophase kuv, metaphase kuv, anaphase kuv , telophase I) thiab meiosis II ( prophase II , metaphase II , anaphase II, telophase II). Meiosis tsim gamete genetic ntau haiv neeg nyob rau hauv ob txoj kev: (1) Txoj cai ntawm kev ywj pheej Assortment.

Dab tsi yog tsib kauj ruam ntawm mitosis hauv kev txiav txim?

Lawv kuj yog genetic zoo tib yam rau niam txiv cell. Mitosis muaj tsib theem sib txawv: interphase, prophase , metaphase , anaphase thiab telophase . Cov txheej txheem ntawm kev faib cell tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sijhawm anaphase thiab telophase.
