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).
