Binary fission ("division in half") yog ib hom asexual kev yug me nyuam . Nws yog daim ntawv ntau tshaj ntawm kev yug me nyuam nyob rau hauv prokaryotes xws li kab mob. Nws tshwm sim hauv qee lub celled Eukaryotes zoo li Amoeba thiab Paramoecium. Thaum binary fission , DNA molecule faib thiab tsim ob DNA molecules.

Hais txog qhov no, cov piv txwv ntawm binary fission yog dab tsi?

Binary Fission Hauv Amoeba Rau cov tsiaj xws li Amoeba proteus, kev sib deev kev sib deev yog ua tiav los ntawm binary fission (ib daim ntawv ntawm asexual reproduction). Txawm li cas los xij, nws kuj tseem tuaj yeem koom nrog ntau yam fission los yog sporulation. Raws li yog cov ntaub ntawv nrog Paramecium, kuj yog ib tug eukaryote, genetic khoom yog replicated los ntawm mitosis.

Tsis tas li ntawd, 4 kauj ruam hauv binary fission yog dab tsi? Cov kauj ruam koom nrog hauv cov kab mob binary fission yog:

  • Kauj Ruam 1 - Rov ua dua ntawm DNA. Cov kab mob uncoils thiab rov ua dua nws cov chromosome, qhov tseem ceeb dua nws cov ntsiab lus.
  • Kauj Ruam 2 - Kev Loj Hlob ntawm Cell.
  • Kauj Ruam 3-Segregation ntawm DNA.
  • Kauj Ruam 4 - Sib cais ntawm Cells.

Hauv qhov no, dab tsi ua rau binary fission?

Kab mob binary fission yog cov txheej txheem uas cov kab mob siv los ua cov cell faib. Thaum cov cell faib los ntawm mitosis nyob rau hauv lub cev ntawm ib tug multicellular kab mob, lawv ua rau cov kab mob kom loj hlob los yog hloov cov qub qub, worn-out cells nrog cov tshiab.

Puas yog eukaryotes rov tsim dua los ntawm binary fission?

Lawv yug me nyuam siv tus txheej txheem hu ua binary fission . Eukaryotic cell feature ib lub voj voog ntawm tes thiab yug me nyuam kev sib deev siv cov txheej txheem ntawm mitosis thiab cytokinesis. Qee qhov kev zam rau "tsuas yog prokaryotes tau txais binary fission "Txawm li cas los xij, txoj cai, ua muaj.
