Cov kws tshawb fawb tau lees paub (Tshaj tawm xyoo 1953 hauv "Nature") nrog rau nrhiav pom ntawm qauv ntawm DNA . Txawm hais tias Watson thiab Crick tau suav nrog nrhiav pom , lawv yuav tsis tau paub txog cov qauv yog lawv tsis pom kev tshawb fawb los ntawm Rosalind Franklin thiab Maurice Wilkins.

Ib yam li ntawd, koj tuaj yeem nug, leej twg nrhiav tau tus qauv ntawm DNA molecule?

Qhov Discovery ntawm DNA's Structure. Coj hauv xyoo 1952, daim duab no yog thawj daim duab X-ray ntawm DNA, uas coj mus rau kev tshawb pom ntawm nws cov qauv molecular los ntawm Watson thiab Crick . Tsim los ntawm Rosalind Franklin siv cov txheej txheem hu ua X-ray crystallography, nws tau nthuav tawm cov duab helical ntawm DNA molecule.

Qhov thib ob, Maurice Wilkins thiab Rosalind Franklin lub luag haujlwm yog dab tsi hauv kev txiav txim siab tus qauv ntawm DNA? DNA hu. Wilkins pib kawm nucleic acids thiab proteins ntawm X-ray duab. Nws ua tau zoo heev nyob rau hauv cais ib leeg fibers ntawm DNA thiab twb tau sau qee cov ntaub ntawv hais txog nucleic acid qauv thaum Rosalind Franklin , tus kws tshaj lij hauv X-ray crystallography, tau koom nrog chav tsev.

Ua li no, Watson thiab Crick nrhiav tau dab tsi?

Nws pom tias ntau cov proteins muab kauv zoo li lub caij nplooj ntoos hlav coil-ib qho alpha helix. Nws lub hom phiaj tom ntej yog sim thiab daws cov qauv ntawm D. N. A. Watson thiab Crick txiav txim siab tias lawv yuav xyaum Linus 'kev ua haujlwm kom tawg cov qauv ntawm D. N. A. ua ntej nws ua.

Wilkins thiab Franklin Discover Quizlet yog dab tsi?

DNA yog cov khoom siv caj ces ntawm T2 phage. sulfur los sau cov phage cov proteins.
