tej hom yog cov kab mob Thermus aquaticus , pom nyob rau hauv lub qhov dej kub ntawm Yellowstone. Los ntawm lub cev yog cais Taq polymerase, lub tshav kub-resistant enzyme tseem ceeb rau DNA-amplification txheej txheem dav siv nyob rau hauv kev tshawb fawb thiab kev kho mob diagnostics (saib polymerase saw cov tshuaj tiv thaiv).
Ua kom pom qhov no, Thermus aquaticus tau txais nws lub zog li cas?
Thermus aquaticus tuaj yeem muaj sia nyob hauv qhov kub li ntawm 50 ° C mus rau 80 ° C, thiab kev loj hlob zoo ntawm kwv yees li 70 ° C. Cov cylindrical kab mob yog ib tug chemotroph uas nws nce zog los ntawm tus oxidation ntawm electron pub.
Tsis tas li ntawd, 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.
Kuj nug, dab tsi yog lub hauv paus ntawm Taq polymerase?
Ib qho thermostable DNA polymerase hu ua Cov tshuaj polymerase yog siv rau polymerization hauv PCR . Nws tau txais los ntawm ib hom kab mob, Thermus aquaticus, uas ib txwm nyob hauv cov dej kub.
Vim li cas Thermus aquaticus tseem ceeb?
Nws yog lub hauv paus ntawm lub tshav kub-resistant enzyme Taq DNA polymerase, ib qho ntawm feem ntau tseem ceeb enzymes nyob rau hauv molecular biology vim nws siv nyob rau hauv lub polymerase saw cov tshuaj tiv thaiv (PCR) DNA amplification txheej txheem.
