Hauv biology, meiosis yog tus txheej txheem uas ib tug diploid eukaryotic cell faib los tsim plaub haploid hlwb feem ntau hu ua gametes. Meiosis Nws yog ib qho tseem ceeb rau kev sib deev kev sib deev thiab yog li ntawd tshwm sim nyob rau hauv tag nrho cov eukaryotes (xws li ib leeg-celled kab mob ) uas yug me nyuam.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi kab mob ua meiosis?
Meiosis tshwm sim nyob rau hauv tag nrho cov kev sib deev-producing ib leeg-celled thiab multicellular kab mob (uas yog tag nrho cov eukaryotes), nrog rau cov tsiaj, nroj tsuag thiab fungi. Nws yog ib qho tseem ceeb rau oogenesis thiab spermatogenesis.
Qhov thib ob, hom kab mob twg siv mitosis? Mitosis plays ib qho tseem ceeb nyob rau hauv lub neej voj voog ntawm feem ntau muaj sia nyob, tab sis mus rau ntau yam. Hauv cov kab mob unicellular xws li cov kab mob, mitosis yog ib hom kev yug me nyuam, ua cov ntawv luam ntawm ib leeg. cell . Hauv cov kab mob multicellular, mitosis tsim ntau dua hlwb rau kev loj hlob thiab kho.
Tsuas yog li ntawd, qhov twg meiosis tshwm sim hauv cov kab mob?
Teb thiab piav qhia: Meiosis siv qhov chaw nyob rau hauv lub cev xeeb tub ntawm lub kab mob . Rau cov poj niam, meiosis yuav siv qhov chaw nyob rau hauv lub zes qe menyuam, qhov twg cov qe raug tsim thiab
Puas yog cov kab mob haploid raug mob meiosis?
Yog lawm, cov kab mob haploid kuj muaj a meiosis nyob rau hauv lawv lub neej voj voog. Feem ntau diploid kab mob nkaus xwb raug meiosis . Tab sis nyob rau hauv ib co cov kab mob haploid tab tom ua kev sib deev kev sib deev, rau haploid gametes fuse los ua rau diploid zygote. Lub zygote ntawd nyob rau hauv meiosis los tsim lub cev haploid.

Cov kab mob puas kis cov kab mob eukaryotic?
Ib lub cell uas muaj kab mob ua rau cov kab mob kis tau ntau dua thiab cov khoom siv caj ces es tsis yog nws cov khoom qub. Qee cov kab mob yuav nyob twj ywm hauv cov tswv tsev rau lub sijhawm ntev, ua rau tsis muaj kev hloov pauv hauv lawv cov tswv tsev (ib theem hu ua lysogenic theem). Cov kab mob ua rau muaj ntau yam kab mob hauv eukaryotes
Cov tshuaj tua kab mob twg thaiv cov kab mob protein ntau?
Tetracyclins yog ib hom tshuaj tua kab mob uas suav nrog cov thawj tetracycline nrog rau doxycycline thiab minocycline. Cov tshuaj tua kab mob no khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas mus rau ribosome, ces tsis muaj cov proteins tshiab tuaj yeem ua tau
Cov kab mob twg muaj cov kab mob eukaryotic?
Cov kab mob thiab Archaea tsuas yog prokaryotes. Cov kab mob uas muaj eukaryotic hlwb hu ua eukaryotes. Tsiaj txhu, nroj tsuag, fungi, thiab protists yog eukaryotes. Tag nrho cov kab mob multicellular yog eukaryotes
Cov kab mob thiab cov kab mob ua haujlwm zoo li cas?
Ob leeg cov kab mob thiab cov kab mob muaj cov phab ntsa ntawm tes (txawm hais tias sib txawv hauv cov qauv thiab muaj pes tsawg leeg) Feem ntau cov kab mob thiab cov kab mob tau txais lub zog los ntawm kev ua pa aerobic (ua pa hauv cov kab mob me ntsis txawv dua li hauv Eukaryotes tab sis cov pa oxygen ib txwm xav tau rau oxidise suab thaj, hauv dej kawg. thiab carbon dioxide yog tsim)
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
