Anaphase of Mitosis vs Anaphase I ntawm Meiosis
Kev sib deev thiab kev sib deev tuaj yeem pom hauv ob peb lub neej eukaryotic. Cov xeeb leej xeeb ntxwv ntawm asexual reproduction yog genetically zoo tib yam rau ib leeg thiab kuj zoo tib yam rau lawv niam lawv txiv, hos cov xeeb ntxwv ntawm kev sib deev kev sib deev sib txawv ntawm ib leeg thiab kuj txawv ntawm lawv niam lawv txiv. Mitosis tshwm sim nyob rau hauv asexual reproduction los yog nyob rau hauv somatic hlwb, tab sis meiosis tshwm sim tsuas yog nyob rau hauv kev sib deev reproduction. Ob leeg Mitosis thiab Meiosis tuaj yeem faib ua Prophase, Metaphase, Anaphase thiab Telophase. Muaj ob qhov Anaphases, hu ua Anaphase I thiab Anaphase II, tshwm sim hauv Meiosis vim yog ob qhov kev sib faib ua tiav nuclear. Anaphase I muaj ob peb qhov sib txawv, txawm tias Anaphase II yog tib yam li Anaphase pom hauv mitosis.
Anaphase of Mitosis
Kev tshem tawm ntawm tus muam chromatids ntawm txhua tus chromosome tau tshwm sim hauv mitotic Anaphase. Shortening ntawm spindle microtubules thiab txav viv ncaus chromatids mus rau cov ncej sab nraud kuj yog tshwj xeeb rau theem no. Qhov kev txav no yog tsav los ntawm lub cev muaj zog proteins. Lwm cov microtubules uas sib tshooj ntawm spindle kuj tseem pab thawb cov ncej kom deb li deb.
Anaphase I of Meiosis
Anaphase I tshwm sim tom qab Metaphase I hauv Meiosis I. Cov chromosomes duplicated tau sib cais thaum lub sijhawm no. Txhua homologues chromosome yog txav mus rau qhov sib txawv ntawm cov ncej ntxaiv vim qhov shortening ntawm spindle fibers. Lub cev muaj zog cov protein uas khi nrog microtubules tswj cov txheej txheem no. Thaum kawg ntawm Anaphase kuv, tag nrho cov homologues chromosomes nyob ze ntawm tus ncej ntxaiv.
Qhov txawv ntawm Anaphase ntawm Mitosis thiab Anaphase I ntawm Meiosis yog dab tsi?
• Kev sib cais thiab txav ntawm tus muam chromatids ntawm txhua tus chromosomes tshwm sim hauv Anaphase of Mitosis thaum sib cais thiab txav ntawm homologous chromosomes mus rau opposite spindle ncej tshwm sim hauv Anaphase I ntawm Meiosis.
• Lub cleavage ntawm centromere yog tshwm sim nyob rau hauv Anaphase ntawm Mitosis, whereas nws tsis tshwm sim nyob rau hauv Anaphase I ntawm meiosis.
• Anaphase I ntawm meiosis tshwm sim hauv cov qe menyuam thaum Anaphase ntawm mitosis tshwm sim hauv cov hlwb somatic.
