Qhov Tseem Ceeb - Interphase vs Prophase
Interphase thiab prophase yog ob theem ntawm lub voj voog ntawm tes. Qhov sib txawv tseem ceeb ntawm interphase thiab prophase yog tias lub xov tooj ntawm tes siv sijhawm ntau hauv interphase ua cov protein synthesis, DNA replication, thiab kev loj hlob thaum lub cell siv sij hawm luv luv hauv prophase los ntawm kev ua kom cov chromatin, ua ke ntawm homologous chromosomes thiab spindle fiber tsim..
Lub xovtooj ntawm tes yog cov qauv tsim thiab ua haujlwm ntawm cov kabmob muaj sia. Nws yog cov qauv microscopic uas muaj cytoplasm, nucleus, organelles thiab vacuole ncig los ntawm ib daim nyias nyias. Cells faib thiab ua cov cell tshiab nyob rau hauv multicellular kab mob thaum lub sij hawm kev loj hlob thiab kev loj hlob. Cov xwm txheej uas ib lub xovtooj tau dhau los ntawm kev yug menyuam (tsim) los tsim cov menyuam ntxhais tshiab hu ua cell cycle lossis cell division. Muaj ob hom cell voj voog; mitosis thiab meiosis. Mitosis tsim ob lub cell tshiab uas muaj tib yam genetic khoom raws li niam txiv muaj. Meiosis tshwm sim thaum lub sij hawm kev sib deev ntawm tes, thiab nws tsim plaub tus ntxhais hlwb uas muaj ib nrab ntawm cov chromosomes (haploid hlwb). Cov voj voog ntawm tes tau muab faib ua ob peb theem uas yog qhov sib txawv ntawm txhua qhov. Interphase thiab mitotic theem (M theem) yog ob theem loj ntawm lub voj voog ntawm tes. M theem rov muab faib ua plaub theem tseem ceeb; prophase, metaphase, anaphase thiab telophase. Interphase muaj peb theem tseem ceeb; G1 theem, S theem thiab G2 theem. Thaum lub sij hawm interphase, cell npaj rau kev faib. Thaum lub sij hawm prophase, chromatin condenses los ntawm kev ua chromosomes ua ke nrog ib leeg thiab spindle fibers tsim ntawm ob tug ncej.
Dab tsi yog Interphase?
Interphase yog ib theem tseem ceeb ntawm lub voj voog ntawm tes. Nws yog lub sijhawm uas lub cell npaj rau kev faib thiab ua rau cov menyuam ntxhais. Kwv yees li ntawm 91% ntawm tag nrho lub sijhawm ntawm lub voj voog ntawm tes mus rau qhov sib cuam tshuam. Interphase tuaj yeem faib ua peb theem xws li G1 theem (kawg 1 theem), S theem thiab G2 (kawg 2 theem) theem. Interphase yog ua raws li M theem ntawm lub voj voog ntawm tes nyob rau hauv uas lwm cov sub-phase pom muaj xws li prophase, metaphase, anaphase thiab telophase.
G1 theem yog thawj theem kev loj hlob thiab thawj theem ntawm kev sib tshuam. Thaum lub sij hawm G1, cell resumes nws tus nqi siab dua ntawm biosynthetic kev ua si, cell synthesizes proteins, cell nce tus naj npawb ntawm organelles thiab cell loj hlob. G1 theem yog ua raws li S theem. Thaum lub sij hawm S theem, DNA replicates (duplicates). Tag nrho cov chromosomes replicate muaj ob tug muam chromatids.

G2 theem yog theem peb ntawm kev sib tshuam. Nws tseem hu ua theem kev loj hlob thib ob. Thaum lub sij hawm G2, cov protein synthesis tshwm sim, thiab cell qhia tau hais tias kev loj hlob sai los pib kev faib cell. Thiab tseem thaum lub sij hawm G2, microtubules pib tsim spindle fibers. Tom qab G2 theem, interphase ua tiav thiab lub xovtooj tau npaj txhij rau kev faib tawm nuclear los tsim cov ntxhais tshiab.
Prophase yog dab tsi?
Prophase yog thawj theem ntawm mitotic theem ntawm lub voj voog ntawm tes. Prophase khiav rau lub sijhawm luv luv. Prophase pib tom qab G2 theem ntawm interphase. Thaum lub sij hawm prophase, chromatin condenses, thiab nucleolus ploj. Chromosome condensation tuaj yeem pom los ntawm ntau yam stains thaum lub sijhawm prophase.
Daim duab 02: Prophase
Ntxiv mus, thaum lub sijhawm prophase, txav ntawm centrosomes tshwm sim, thiab tsim cov spindle fibers pib. Nyob rau hauv mitotic cell division, tsuas yog ib tug prophase tshwm thaum nyob rau hauv meiosis ob prophases pom. Prophase yog ua raws li metaphase.
Dab tsi yog qhov zoo sib xws ntawm Interphase thiab Prophase?
- Ob qhov Interphase thiab Prophase yog ob theem ntawm kev faib cell.
- Ob theem Interphase thiab Prophase yog qhov tseem ceeb hauv cov kab mob ntau lub cev.
Qhov txawv ntawm Interphase thiab Prophase yog dab tsi?

Summary – Interphase vs Prophase
Interphase thiab prophase yog ob theem ntawm lub voj voog ntawm tes ntawm ntau cov kab mob. Interphase yog thawj theem loj ntawm lub voj voog ntawm tes uas muaj peb theem tseem ceeb xws li G1 theem, S theem thiab G2 theem. Ib lub xovtooj siv sijhawm ntev dua hauv kev cuam tshuam vim yog kev npaj ntawm lub xovtooj rau kev faib tawm nuclear thiab tsim cov hlwb tshiab. Prophase yog thawj theem ntawm mitotic theem, thiab nws pib tom qab interphase. Thaum lub sij hawm prophase, lub cell nres lub cell loj hlob thiab pib lub cell division. Chromatin condenses, thiab spindle fibers tsim nyob rau theem no. Qhov no yog qhov txawv ntawm interphase thiab prophase.
