Franklin paub zoo tshaj plaws rau nws txoj haujlwm ntawm X-ray diffraction dluab ntawm DNA , tshwj xeeb yog Daim Duab 51, thaum nyob hauv King's College London, uas coj mus rau 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, Rosalind Franklin tau pab txhawb rau DNA xyoo twg?

Rosalind Elsie Franklin (25 Lub Xya Hli 1920 - 16 Plaub Hlis 1958)[1] yog ib tug British biophysicist thiab X-ray crystallographer uas ua qhov tseem ceeb kev pab kom nkag siab txog cov qauv zoo molecular ntawm DNA , RNA, kab mob, thee thiab graphite.

Ib yam li ntawd, Rosalind Franklin tau ua lub luag haujlwm dab tsi hauv kev tshawb pom cov qauv ntawm DNA? Ntawm King's College London, Rosalind Franklin tau cov duab ntawm DNA siv X-ray crystallography, ib lub tswv yim ua ntej broached los ntawm Maurice Wilkins. Franklin tus dluab tso cai rau James Watson thiab Francis Crick los tsim lawv lub npe nrov ob-strand, lossis ob-helix, qauv.

Hais txog qhov no, leej twg yog Rosalind Franklin thiab nws nrhiav tau dab tsi?

British kws tshuaj Rosalind Franklin Nws yog qhov paub zoo tshaj plaws rau nws lub luag haujlwm hauv kev tshawb pom cov qauv ntawm DNA, thiab rau nws txoj kev siv X-ray diffraction.

Leej twg nrhiav tau DNA tiag tiag?

Ntau tus neeg ntseeg tias American biologist James Watson thiab English physicist Francis Crick nrhiav DNA hauv xyoo 1950. Qhov tseeb, qhov no tsis yog li ntawd. Hloov chaw, DNA tau pom thawj zaug hauv 1860s lig los ntawm Swiss chemist Friedrich Miescher.
