Qauv. Kab mob (singular: kab mob ) yog cais raws li prokaryotes, uas yog Cov kab mob ib leeg nrog ib qho yooj yim sab hauv cov qauv uas tsis muaj ib tug nucleus, thiab muaj DNA uas yog floats dawb do nyob rau hauv ib tug twisted, xov zoo li loj hu ua lub nucleoid, los yog nyob rau hauv cais, ncig daim ntawv hu ua plasmids.
Kuj paub, txhais li cas ntawm cov kab mob cell?
Kab mob Cell Qauv. Kab mob yog prokaryotes, tsis zoo txhais nuclei thiab membrane-bound organelles, thiab nrog 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.
Kuj Paub, kab mob cell txawv li cas ntawm tib neeg cell? HUMAN CELL YOG A EUKARYOTIC CELL KUV XAV KOM A Kab mob YOG PROKARYOTIC CELL . LUB BABTERIAL CELL YOG A CELL PUAS YOG. Lawv DNA yog dawb floating nyob rau hauv lub cytoplasm.
Qhov thib ob, tus kab mob cell zoo li cas?
Kab mob yog nyiam eukaryotic tshuaj hlwb Nyob rau hauv hais tias lawv muaj cytoplasm, ribosomes, thiab ib tug plasma membrane. Cov yam ntxwv uas paub qhov txawv a kab mob cell los ntawm eukaryotic cell suav nrog cov DNA ncig ntawm nucleoid, tsis muaj daim nyias nyias-bound organelles, lub cell phab ntsa ntawm peptidoglycan, thiab flagella.
Cov kab mob ua haujlwm li cas?
Kab mob nyob rau hauv lub digestive system zom cov as-ham, xws li complex suab thaj, rau hauv daim ntawv ntawm lub cev ua tau siv. Tsis muaj teeb meem kab mob kuj pab tiv thaiv kab mob los ntawm kev nyob qhov chaw uas cov kab mob, los yog kab mob ua rau, kab mob xav rau txuas rau . Ib txhia kab mob tiv thaiv peb ntawm kab mob los ntawm kev tawm tsam cov kab mob.

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 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)
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
