Thaum interphase , lub xov tooj ntawm tes luam nws DNA hauv kev npaj rau mob mitosis . Ib qho kev xav tsis zoo yog qhov ntawd interphase yog cov thawj theem ntawm mitosis , tab sis txij li thaum mob mitosis yog kev faib ntawm cov nucleus, prophase yog qhov tiag thawj theem . Hauv interphase , lub cell tau txais nws tus kheej npaj rau mob mitosis los yog meiosis.

Ib yam li ntawd, tib neeg nug, dab tsi yog thawj theem ntawm mitosis?

Prophase

Dab tsi yog 5 theem ntawm mitosis? Lawv kuj yog genetic zoo tib yam rau niam txiv cell. Mitosis muaj tsib theem sib txawv: interphase , prophase , metaphase , kev anaphase thiab telophase . Cov txheej txheem ntawm kev faib cell tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sijhawm kev anaphase thiab telophase.

Ib yam li ntawd, koj tuaj yeem nug, 7 theem ntawm mitosis yog dab tsi?

Cov ntsiab lus hauv cov teeb no (7)

  • Interphase. Cell ua haujlwm li qub, Cell loj hlob (G1 thiab g2), Synthesizes tshiab molecules thiab organelles.
  • Prophase.
  • Prometaphase.
  • Metaphase.
  • Anaphase.
  • Telophase.
  • Cytokinesis.

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

Interphase yog tsim los ntawm G1 theem (kev loj hlob ntawm tes), ua raws li S theem (DNA synthesis), ua raws li G2 theem (kev loj hlob ntawm tes). Thaum kawg ntawm interphase los ntawm mitotic theem , uas yog tsim los ntawm mitosis thiab cytokinesis thiab ua rau kev tsim ntawm ob tug ntxhais hlwb.
