Thermus aquaticus yog ib hom kab mob uas tuaj yeem tiv taus qhov kub thiab txias, ib qho ntawm ntau cov kab mob thermophilic uas muaj nyob hauv Deinococcus - Thermus pab pawg.
Cov lus nug tseem yog, puas yog Thermus aquaticus eukaryotic?
Prokaryotic DNA Polymerases Organelles nyob rau hauv lub eukaryotic tshuaj cell, xws li mitochondria, tej zaum yuav muaj DNA uas kuj yuav tsum tau replicated. Prokaryotic chromosomes yog ncig, whereas eukaryotic tshuaj chromosomes yog linear. DNA polymerase III α-subunit qhia hauv qab no yog ntawm Thermus aquaticus , feem ntau hu ua Taq.
Ib yam li ntawd, cov kab mob dab tsi yog Taq polymerase los ntawm? Taq DNA Polymerase yog Ameslikas cais los ntawm cov kab mob thermophilic ntawm tus Deinococcus -Thermus pab pawg nyob ze ntawm Lower Geyser Basin ntawm Yellowstone National Park los ntawm Thomas D. Brock thiab Hudson Freeze, xyoo 1969. Cov kab mob loj hlob no tau hu ua Thermus aquaticus (T. aquaticus).
Ib yam li ntawd, dab tsi tau txais los ntawm cov kab mob Thermus aquaticus?
Cov kab mob Thermus aquaticus yog lub tshav kub labile kab mob uas tau txais los ntawm cov dej kub ntawm qhov kub thiab txias tshaj 97-degree centigrade. Qhov no kab mob tsim ib qho enzyme Taq polymerase uas yog thermostable thiab ua haujlwm txawm nyob rau hauv qhov kub thiab txias thiab ua rau lub denaturation ntawm ob-stranded DNA.
Thermus aquaticus nyob qhov twg?
cov hom no yog cov kab mob Thermus aquaticus , pom nyob rau hauv lub qhov dej kub ntawm Yellowstone. Los ntawm cov kab mob no tau raug cais tawm Taq polymerase, lub tshav kub-resistant enzyme tseem ceeb rau DNA-amplification txheej txheem dav siv hauv kev tshawb fawb thiab kev kho mob (saib cov tshuaj tiv thaiv polymerase saw).

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
