Oswald Theodore Avery Jr.
Avery yog ib tus thawj kws tshawb fawb txog molecular biologists thiab ib tug pioneer hauv immunochemistry, tab sis nws paub zoo tshaj plaws rau kev sim (tshaj tawm xyoo 1944 nrog nws cov neeg ua haujlwm Colin MacLeod thiab Maclyn McCarty ) uas cais DNA raws li cov khoom ntawm cov noob caj noob ces thiab chromosomes raug tsim.
Ntawm no, Avery thiab nws cov npoj yaig nrhiav tau dab tsi?
Cov nrhiav pom tau hu ua "txoj cai hloov pauv" thiab dhau los nws kev sim, Avery thiab nws Cov neeg ua haujlwm sib koom ua ke pom tias qhov hloov pauv ntawm cov kab mob yog vim DNA. Yav dhau los, cov kws tshawb fawb xav tias qhov zoo li no tau nqa los ntawm cov protein, thiab DNA tau yooj yim dhau los ua cov khoom ntawm cov noob.
Oswald Avery nrhiav tau thaum twg? Nyob rau 1 Lub Ob Hlis 1944, Phau ntawv Journal of Experimental Medicine tau luam tawm ib qho kev tshawb pom ntawm lub xyoo pua 20th: Oswald Avery (1877–1955), ua ke nrog nws cov npoj yaig Colin MacLeod (1909–1972) thiab Maclyn McCarty (1911–2005), qhia tias kev hloov pauv ntawm cov kab mob pneumococcus ntawm ib hom mus rau lwm qhov.
Tom qab ntawd, Avery qhov kev sim ua pov thawj dab tsi?
Oswald Avery , Colin MacLeod, thiab Maclyn McCarty tau qhia tias DNA (tsis yog cov proteins) tuaj yeem hloov cov khoom ntawm cov hlwb, qhia meej txog cov tshuaj ntawm cov noob. Avery , MacLeod thiab McCarty tau txheeb xyuas DNA raws li "txoj cai hloov pauv" thaum kawm Streptococcus pneumoniae, cov kab mob uas tuaj yeem ua rau mob ntsws.
maclyn McCarty nrhiav tau dab tsi?
Maclyn McCarty (Lub Rau Hli 9, 1911 - Lub Ib Hlis 2, 2005) yog ib tug neeg Asmeskas caj ces. Maclyn McCarty , uas tau mob siab rau nws lub neej ua tus kws kho mob-tus kws tshawb fawb los kawm cov kab mob sib kis, tau paub zoo tshaj plaws rau nws txoj haujlwm hauv qhov kev tshawb pom loj heev uas DNA, tsis yog cov protein, tsim cov tshuaj lom neeg ntawm cov noob.

Archimedes yog leej twg thiab nws nrhiav tau dab tsi?
Archimedes, (yug c. 287 bce, Syracuse, Sicily [Italy]-tuag 212/211 bce, Syracuse), tus kws ua lej nto moo tshaj plaws thiab tus tsim khoom hauv tebchaws Greece thaum ub. Archimedes yog qhov tseem ceeb tshwj xeeb rau nws qhov kev tshawb pom ntawm kev sib raug zoo ntawm qhov chaw thiab ntim ntawm ib puag ncig thiab nws lub tog raj kheej ncig
Clair Patterson nrhiav tau dab tsi?
Clair Patterson yog ib tus neeg muaj zog, muaj tswv yim tshiab, txiav txim siab tus kws tshawb fawb uas nws cov thawj coj ua haujlwm tau nthuav dav thoob plaws cov kev qhuab qhia txawv txawv, suav nrog archaeology, meteorology, oceanography, thiab ib puag ncig kev tshawb fawb-nrog rau chemistry thiab geology. Nws paub zoo tshaj plaws rau nws qhov kev txiav txim siab ntawm lub hnub nyoog ntawm Lub Ntiaj Teb
Griffith thiab Avery nrhiav tau dab tsi?
Frederick Griffith thiab Oswald Avery yog cov kws tshawb fawb tseem ceeb hauv kev tshawb pom DNA. Griffith yog ib tug kws kho mob Askiv thiab kws tshuaj caj ces. Xyoo 1928, niaj hnub no hu ua Griffith qhov kev sim, nws pom qhov nws hu ua 'txoj cai hloov pauv' uas ua rau muaj qub txeeg qub teg
Yuav ua li cas koj thiaj nrhiav tau tus nqi ntawm tus qauv txhais tau tias?
Qhov xav tau tus nqi ntawm tus qauv txhais tau tias yog cov pej xeem txhais tau tias, thiab SE ntawm tus qauv txhais tau tias yog SD ntawm cov pej xeem, muab faib los ntawm lub hauv paus square ntawm tus qauv loj
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
