Qhov sib txawv tseem ceeb ntawm prophase thiab metaphase yog tias, hauv prophase, chromosomes condense thiab spindle fiber formsthaum, hauv metaphase, chromosomes kab nyob rau hauv nruab nrab ntawm lub cell thiab centromeres txuas rau spindle fibers.
prophase kuv txawv ntawm prophase li cas?
Prophase I yog theem pib ntawm Meiosis I thaum Prophase II yog theem pib ntawm Meiosis II. Muaj qhov cuam tshuam ntev ua ntej Prophase I, qhov Prophase II tshwm sim yam tsis muaj kev cuam tshuam. Kev sib koom ua ke ntawm homologous chromosomes tshwm sim hauv Prophase I, qhov txheej txheem no tsis tuaj yeem pom hauv Prophase II.
Puas yog prophase lossis metaphase ua ntej?
Metaphase yog theem ntawm mitosis uas follows prophase thiab prometaphase thiab ua ntej anaphase. Metaphase pib thaum tag nrho cov kinetochore microtubules tau txuas mus rau tus muam chromatids 'centromeres thaum lub sij hawm prometaphase.
Koj paub qhov prophase li cas?
Prophase Under a Microscope
Thaum koj saib ib lub xovtooj ntawm prophase nyob rau hauv lub microscope, koj yuav pom thick strands ntawm DNA xoob nyob rau hauv lub cell. Yog tias koj tab tom saib cov prophase ntxov, koj tseem yuav pom cov nucleolus tsis zoo, uas zoo li ib puag ncig, tsaus blob.
Yuav ua li cas prophase txawv ntawm interphase?
Chromosomes txuas nrog lub tshuab spindle thaum lub sijhawm prophase. Qhov sib txawv tseem ceeb ntawm interphase thiab prophase yog qhov thaum interphase, cell loj hlob los ntawmnce qhov loj thiab duplicating cov genetic khoom whereas, thaum lub sij hawm prophase, tiag cell division pib los ntawm chromosome condensing.
