Tsim los ntawm Rosalind Franklin siv cov txheej txheem hu ua X-ray crystallography, nws nthuav tawm cov duab helical ntawm DNA molecule. Watson thiab Crick pom tau hais tias DNA yog tsim los ntawm ob txoj hlua ntawm nucleotide khub uas encode cov ntaub ntawv caj ces rau txhua yam muaj sia.
Watson thiab Crick nrhiav tau dab tsi hauv xyoo 1953?
Yog tsis muaj lub hauv paus kev tshawb fawb muab los ntawm cov pioneers no, Watson thiab Crick yuav tsis tau mus txog qhov kawg ntawm xyoo 1953: DNA molecule muaj nyob rau hauv daim ntawv ntawm peb-dimensional helix.
Puas Watson thiab Crick nrhiav tau dab tsi?
Qhov kev tshawb pom hauv 1953 ntawm ob lub helix, tus qauv twisted-ladder ntawm deoxyribonucleic acid (DNA), los ntawm James Watson thiab Francis Crick cim lub ntsiab lus tseem ceeb hauv keeb kwm ntawm kev tshawb fawb. thiab tau ua rau niaj hnub molecular biology, uas muaj kev txhawj xeeb loj nrog kev nkag siab tias cov noob tswj cov txheej txheem tshuaj li cas hauv …
Watson Crick Franklin thiab Wilkins nrhiav tau dab tsi?
Xyoo 1962, James Watson, Francis Crick thiab Maurice Wilkins tau txais txiaj ntsig Nobel rau qhov kev tshawb pom ntawm tus qauv ntawm DNA. Qhov tshwj xeeb tsis tuaj ntawm lub podium yog Rosalind Franklin, nws cov duab X-ray ntawm DNA tau pab ncaj qha rau kev tshawb pom ntawm ob lub helix.
Crick thiab Watson nrhiav DNA qhov twg?
At King's College London, Rosalind Franklin tau txais cov duab ntawm DNA siv X-ray crystallography, ib lub tswv yim thawj zaug los ntawm Maurice Wilkins. Franklin cov duab tso cai rau James Watson thiab Francis Crick los tsim lawv lub npe nrov ob-strand, lossis ob-helix, qauv.
