Franklin paub zoo tshaj plaws rau nws txoj haujlwm ntawm X-ray diffraction dluab ntawm DNA, tshwj xeeb tshaj yog Photo 51, thaum nyob rau ntawm King's College London, uas coj mus rau lub nrhiav pom ntawm DNA ob lub helix uas James Watson, Francis Crick thiab Maurice Wilkins tau qhia txog Nobel nqi zog hauv Physiology lossis Tshuaj hauv xyoo 1962.
Raws li txoj cai, vim li cas Rosalind Franklin qhov kev tshawb pom tseem ceeb?
Nws qhia nws X-ray diffraction, uas yuav ua si tseem ceeb lub luag haujlwm hauv nws txoj kev tshawb fawb uas coj mus rau qhov nrhiav pom ntawm "qhov zais cia ntawm lub neej" - tus qauv ntawm DNA. Ntxiv rau, Franklin pioneered siv X-rays los tsim cov duab ntawm crystalized solids nyob rau hauv kev soj ntsuam complex, unorganized teeb meem, tsis yog ib tug crystals.
Tsis tas li ntawd, Rosalind Franklin qhov kev pab cuam rau kev tshawb fawb yog dab tsi? Rosalind Elsie Franklin (25 Lub Xya Hli 1920 - 16 Lub Plaub Hlis 1958)[1] yog ib tug kws tshawb fawb Askiv thiab X-ray crystallographer uas tau ua qhov tseem ceeb. kev pab kom nkag siab txog cov qauv zoo molecular ntawm DNA, RNA, kab mob, thee thiab graphite.
Tom qab ntawd, ib tug kuj yuav nug, Rosalind Franklin nrhiav tau hloov lub ntiaj teb no li cas?
Rosalind Franklin tus Kev tshawb fawb tau coj mus rau Discovery ntawm DNA Structure. Nws txoj kev tshawb fawb tau pab daws qhov tsis meej ntawm cov qauv ntawm DNA - lub tsev thaiv ntawm lub neej. Xyoo 1952, Franklin coj cov duab X-Ray ntawm ib lub molecule uas pom DNA muaj ob txoj hlua qhwv ib ncig ntawm ob lub helix, zoo li tus ntaiv twisted.
Rosalind Franklin tuag li cas?
Ovarian cancer

Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm lub teeb pom kev thiab pom tsis pom?
Tsis muaj qhov sib txawv ntawm lub teeb pom kev thiab pom tsis pom lub teeb xws li xov tooj cua nthwv dej thiab X rays. Lawv yog tag nrho cov electromagnetic tsis txawv nyob rau hauv ib txoj kev xwb: lawv wavelength. Lub teeb ultraviolet, X rays, thiab gamma rays tag nrho muaj luv luv wavelengths tshaj li pom lub teeb
Dab tsi yog qhov kev tshawb pom uas txhawb nqa kev nthuav dav hauv hiav txwv?
Cov ntaub ntawv pov thawj rau Sea-Floor Spreading. Ob peb hom pov thawj txhawb Hess txoj kev xav ntawm hiav txwv-floorspreading: eruptions ntawm molten khoom, sib nqus kab txaij nyob rau hauv lub pob zeb ntawm lub hiav txwv pem teb, thiab lub hnub nyoog ntawm lub rocksthem tus kheej. Cov pov thawj no ua rau cov kws tshawb fawb rov qab saib dua ntawm Wegener'shypothesis ntawm kev sib tw sab av loj
Dab tsi yog chromosome txoj kev xav ntawm kev qub txeeg qub teg thiab nws cuam tshuam li cas rau Mendel qhov kev tshawb pom?
Piav Mendel cov lus xaus txog qhov zoo li cas dhau ntawm ib tiam dhau ib tiam. Lub chromosome txoj kev xav ntawm kev qub txeeg qub teg hais tias cov yam ntxwv qub txeeg qub teg yog tswj los ntawm cov noob nyob rau ntawm chromosomes ncaj ncees kis los ntawm gametes, tswj cov caj ces txuas ntxiv ntawm tiam mus rau ib tiam
Thaum twg Rosalind Franklin pab txhawb rau kev tshawb pom DNA?
Franklin paub zoo tshaj plaws rau nws txoj haujlwm ntawm X-ray diffraction dluab ntawm DNA, tshwj xeeb tshaj yog Diam duab 51, thaum nyob rau ntawm King's College London, uas coj mus rau qhov kev tshawb pom ntawm DNA ob helix rau James Watson, Francis Crick thiab Maurice Wilkins tau koom lub Nobel. Nqi zog hauv Physiology lossis Tshuaj hauv xyoo 1962
