Cov nrhiav pom tau hu ua "txoj cai hloov pauv" thiab los ntawm nws qhov kev sim, Avery thiab nws cov neeg ua haujlwm tau pom tias kev hloov pauv ntawm cov kab mob yog vim li cas DNA . Yav dhau los, cov kws tshawb fawb tau xav tias cov yam ntxwv zoo li no tau nqa los ntawm cov protein, thiab qhov ntawd DNA yooj yim dhau los ua cov khoom ntawm cov noob.
Ib yam li ntawd, koj tuaj yeem nug, Oswald Avery tau tshawb pom tias DNA yog cov khoom siv caj ces?
Oswald Avery (c. 1930) Hauv kev sim yooj yim heev, Oswald Avery's pab pawg tau pom tias DNA yog "txoj cai hloov pauv." Thaum cais tawm ntawm ib hom kab mob, DNA nws muaj peev xwm hloov tau lwm hom kab mob thiab confer yam ntxwv rau qhov thib ob hom. DNA tau nqa hereditary cov ntaub ntawv.
Tom qab ntawd, lo lus nug yog, 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 British thiab kws tshuaj caj ces. Xyoo 1928, niaj hnub no hu ua Griffith cov kev sim, nws nrhiav pom dab tsi nws hu ua "txoj cai hloov pauv" uas ua rau muaj qub txeeg qub teg.
Yog li ntawd, Oswald Avery nrhiav tau DNA xyoo twg?
1944
Avery siv dab tsi hauv nws qhov kev sim?
Lub Avery - MacLeod-McCarty kev sim yog ib kev sim Kev ua qauv qhia, tshaj tawm xyoo 1944 los ntawm Oswald Avery , Colin MacLeod, thiab Maclyn McCarty, DNA yog tus tshuaj uas ua rau cov kab mob hloov pauv, nyob rau hauv ib lub sij hawm thaum nws muaj tau dav ntseeg tias nws yog cov protein uas ua haujlwm tus muaj nuj nqi ntawm nqa cov caj ces

DNA ob lub helix nrhiav tau li cas?
Qhov Discovery ntawm DNA's Structure. Tsim los ntawm Rosalind Franklin siv cov txheej txheem hu ua X-ray crystallography, nws tau nthuav tawm cov duab helical ntawm DNA molecule. Watson thiab Crick pom tau hais tias DNA tau tsim los ntawm ob txoj hlua ntawm nucleotide khub uas encode cov ntaub ntawv caj ces rau txhua yam muaj sia
DNA replication nrhiav tau li cas?
Matthew Meselson thiab Franklin Stahl qhov kev sim ntawm kev rov ua dua ntawm DNA, luam tawm hauv PNAS hauv xyoo 1958 (2), pab cement lub tswvyim ntawm ob lub helix. Ob tug txiv neej tom qab lub zog ua haujlwm hauv kev tshawb pom qhov kev rov ua dua tshiab ntawm DNA credit ntau ntawm lawv txoj kev vam meej rau lub sijhawm, kev ua haujlwm nyuaj, thiab kev ua haujlwm zoo
Avery nrhiav tau dab tsi?
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 qhov kev sim (tshaj tawm xyoo 1944 nrog nws cov neeg ua haujlwm Colin MacLeod thiab Maclyn McCarty) uas cais DNA raws li cov khoom siv. noob thiab chromosomes yog tsim
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
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
