[AP Biology] Yog vim li cas Prophase Cov theem feem ntau hauv Mitosis? Yog li peb tab tom ua ib qho Dos Root lab qhov twg peb suav thiab nrhiav feem pua ntawm cov hlwb tam sim no tab tom ua Mitosis thiab uas nyob hauv Interphase. Tsis suav nrog interphase, Prophase yog lub sijhawm feem ntau ntawm mitosis, tab sis vim li cas?

Ua raws li qhov no, dab tsi yog theem tseem ceeb tshaj plaws hauv mitosis?

Interphase

Tsis tas li ntawd, qhov tseem ceeb ntawm mitosis yog dab tsi? Mitosis yog ib txoj kev uas ib lub xovtooj sib faib ua ob lub hlwb zoo tib yam (cell division). Thaum mob mitosis ib cell? faib ib zaug los tsim ob lub hlwb zoo ib yam. Lub hom phiaj tseem ceeb ntawm mob mitosis yog rau kev loj hlob thiab hloov pauv cov cell uas ploj lawm.

Kuj nug, dab tsi yog theem tseem ceeb ntawm meiosis?

Prophase

Yog vim li cas prophase yog feem ntau theem nyob rau hauv mitosis?

Cells siv li ntawm 14 feem pua ntawm lub voj voog ntawm tes hauv prophase. Qhov no yog qhov loj tshaj ntawm lub sij hawm siv nyob rau hauv ib theem tom qab interphase . Lub sijhawm no yuav siv sijhawm ntev dua li lwm tus vim tias lub hnab ntawv nuclear tawg thiab cov microtubules yuav tsum tau txuas rau chromosomes . Metaphase raws li prophase.
