Qhov Tseem Ceeb - Interphase vs Mitosis
Interphase thiab mitosis yog ob theem loj ntawm kev faib cell. Interphase yog ua raws li mitosis (M theem) hauv lub voj voog ntawm tes. Qhov sib txawv tseem ceeb ntawm interphase thiab mitosis yog tias interphase yog lub sijhawm ntev tshaj plaws ntawm lub voj voog ntawm tes uas lub cell loj hlob thiab rov ua dua nws cov DNA thaum mitosis yog ib ntus luv luv ntawm lub voj voog ntawm tes uas cell nucleus hloov mus rau hauv ob lub nuclei uas dais zoo tib yam genome. thawj nucleus los tsim ob lub hlwb tshiab.
Ib lub xovtooj siv sijhawm feem ntau ntawm nws lub neej voj voog nyob rau hauv interphase. Interphase los ntawm ob theem ua tiav mitosis. Thaum lub sij hawm interphase, lub cell loj hlob los ntawm accumulating as-ham, synthesizing proteins, ua tshiab organelles thiab replicating nws DNA. Thaum kawg ntawm interphase, lub xovtooj ntawm tes tau npaj rau kev faib cov nucleus thiab tsim cov hlwb tshiab. Mitosis yog theem thib ob loj ntawm lub voj voog ntawm tes uas cov nucleus faib ua ob lub nuclei uas muaj cov noob caj noob ces zoo tib yam rau kev tsim ntawm ob lub hlwb.
Dab tsi yog Interphase?
Interphase yog lub sijhawm ntev tshaj plaws ntawm lub voj voog ntawm tes. Nws txuas rau lub sijhawm ntev (kwv yees li 91% ntawm tag nrho lub sijhawm) ntawm lub voj voog ntawm tes. Nucleolus thiab daim nyias nyias nyias tuaj yeem pom nyob rau hauv interphase.
Daim duab 01: Interphase
Interphase muaj peb theem sub xws li G1 theem, S theem thiab G2 theem. G1 thiab G2 yog ob theem sib txawv. Thaum ob theem no, cell loj hlob, cell accumulates as-ham, cell ua organelles thiab cell synthesize proteins. S theem yog ib theem tseem ceeb uas DNA replication tshwm sim. Thaum kawg ntawm theem S, lub xov tooj ntawm tes muaj ob pawg DNA ua tiav. Thaum lub cell ua tiav interphase, lub cell nkag mus rau theem mitosis (M theem).
Mitosis yog dab tsi?
Mitosis yog theem thib ob loj ntawm lub voj voog ntawm tes. Thaum lub sij hawm mitosis, cell nucleus hloov mus ua ob lub nuclei thiab thaum kawg, cell devised rau hauv ob lub hlwb. Mitosis txuas ntxiv rau lub sijhawm luv luv. Muaj plaub subphases ntawm mitosis uas yog prophase, metaphase, anaphase thiab telophase. Mitosis xaus nrog kev faib cytoplasm thiab dhau los ua ob lub hlwb uas zoo ib yam.
Thaum lub sijhawm prophase, centrosomes tsiv mus rau hauv ob tug ncej ntawm lub xovtooj ntawm tes, nuclear membrane pib ploj mus, microtubules pib txuas ntxiv, chromosomes condense ntau thiab ua ke nrog ib leeg thiab tus muam chromatids pom. Thaum lub sijhawm metaphase, chromosomes kab ntawm lub phaj metaphase thiab microtubules txuas nrog cov centrosomes ntawm kab chromosomes.
Daim duab 02: Mitosis
Metaphase yog ua raws li anaphase uas tus muam chromatids faib sib npaug thiab sib cais kom tsiv mus rau ob tus ncej. Muam chromatids raug rub mus rau ob tug ncej los ntawm microtubules. Thaum lub sij hawm telophase, ob daim ntawv tshiab nuclei thiab pib faib cov ntsiab lus ntawm tes mus rau hauv ob sab ntawm lub cell. Cell cytoplasm faib ua ob lub hlwb tshiab. Cov txheej txheem no hu ua cytokinesis. Tom qab cytokinesis, ob lub hlwb zoo ib yam yuav tsim thiab cov hlwb tshiab yuav txuas ntxiv rov ua lub voj voog ntawm tes.
Dab tsi zoo sib xws ntawm Interphase thiab Mitosis?
- Interphase thiab mitosis yog ob theem ntawm lub voj voog ntawm tes.
- Ob leeg yog cov xwm txheej tseem ceeb ntawm lub voj voog ntawm tes.
- Ob leeg interphase thiab mitosis yog qhov tseem ceeb rau cov kab mob ntau lub cev rau kev loj hlob thiab kev loj hlob.
Qhov txawv ntawm Interphase thiab Mitosis yog dab tsi?
Interphase vs Mitosis |
|
| Interphase yog theem npaj uas tshwm sim nyob rau hauv nruab nrab ntawm ob lub mitotic cell divisions. | Mitosis yog theem ntawm kev faib tawm nuclear uas lub cell faib ua cov hlwb tshiab. |
| theem | |
| Interphase muaj peb theem xws li, G1 theem, S theem, thiab G2 theem. | Mitosis muaj ob theem xws li karyokinesis (prophase, metaphase, anaphase thiab telophase) thiab cytokinesis. |
| Interphase tshwm sim rau lub sijhawm ntev. | Mitosis tshwm sim thaum lub sijhawm luv. |
| Chromosomes | |
| In interphase, chromosomes tsawg condensed. | Thaum mitosis, chromosomes yog condensed heev. |
| Zoo ntawm Chromosomes | |
| In interphase, chromosomes tshwm raws li xov zoo li cov qauv. | Nyob hauv mitosis, chromosomes tshwm raws li tus pas nrig zoo li cov qauv. |
| Centrosomes | |
| Ob centrosomes nyob rau hauv lub cell nucleus thaum lub sij hawm interphase. | Ob lub centrosomes tuaj yeem pom nyob rau hauv ob tug ncej ntawm lub cell thaum lub sij hawm mitosis. |
| Nuclear membrane muaj nyob rau lub sijhawm cuam tshuam. | Nuclear membrane ploj thaum lub sij hawm mitosis. |
| Cytokinesis | |
| Cytokinesis tsis tshwm sim hauv interphase. | Thaum lub sijhawm mitosis, cytokinesis tshwm sim. |
Summary – Interphase vs Mitosis
Interphase thiab mitosis yog ob theem loj ntawm lub voj voog ntawm tes. Interphase npaj lub cell rau kev faib los ntawm replicating nws DNA thiab synthesizing tsim nyog proteins thiab organelles los ntawm kev khiav mus rau lub sij hawm ntev. Mitosis pib tom qab interphase thiab khiav rau lub sijhawm luv luv. Txawm li cas los xij, kev faib tawm ntawm tes tiag tiag tshwm sim thaum lub sijhawm mitosis. Nucleus hloov mus ua ob lub nuclei thiab tsim ob lub cell uas zoo tib yam rau niam txiv cell thaum lub sij hawm mitosis. Qhov no yog qhov txawv ntawm interphase thiab mitosis.
