Phase ntawm mitosis. Mitosis muaj plaub theem pib: prophase , metaphase , kev anaphase , thiab telophase . Qee phau ntawv sau tsib, tawg prophase mus rau theem ntxov (hu ua prophase ) thiab theem lig (hu ua prometaphase).

Tsis tas li ntawd, cov theem ntawm mitosis yog dab tsi?

Mitosis yog ib qho txheej txheem ntawm kev faib cell, uas ib leeg cell faib ua ob lub noob caj noob ces zoo tib yam ntawm cov ntxhais. Tsib theem ntawm mitosis yog interphase, prophase , metaphase , kev anaphase thiab telophase.

Kuj Paub, ntev npaum li cas txhua theem ntawm mitosis? Lub sij hawm xav tau ces rau cov txheej txheem tiav ntawm mitotic Kev faib tawm ntawm tes yuav nyob hauv cov kev txwv hauv qab no: Prophase, 30 mus rau 60 feeb; metaphase, 2 mus rau 10 feeb; anaphase 2 mus rau 3 feeb; telophase 3 mus rau 12 feeb thiab lub sijhawm rov tsim kho los ntawm 30 t'o 120 feeb: tag nrho 70 txog 180 feeb.

Hais txog qhov no, dab tsi yog 4 theem ntawm mitosis thiab dab tsi tshwm sim hauv txhua qhov?

Mitosis yog tus txheej txheem uas lub nucleus ntawm ib tug eukaryotic cell faib. Thaum tus txheej txheem no, tus muam chromatids cais los ntawm txhua lwm yam thiab txav mus rau opposite ncej ntawm lub cell. Qhov no tshwm sim hauv plaub theem , hu ua prophase, metaphase, anaphase, thiab telophase.

Dab tsi yog 9 theem ntawm mitosis?

9 Theem Ntawm Mitosis Thiab Meiosis

  • Prophase (Mitosis) 1. Cov spindle fibers tsim thiab cov centrioles txav mus rau sab nraud ntawm tes.
  • Metaphase (Mitosis) 2. Cov chromosomes nyob nruab nrab ntawm cov spindle fibers.
  • Anaphase (Mitosis) 3.
  • Telophase (Mitosis) 4.
  • Prophase I (Meiosis) 1.
  • Metaphase I (Meiosis) 2.
  • Anaphase I (Meiosis) 3.
  • Telophase I (Meiosis) 4.
