Francis Crick (1916-2004) yog ib tug ntawm Britain tus kws tshawb fawb zoo. Nws paub zoo tshaj plaws rau nws txoj haujlwm nrog James Watson uas coj mus rau kev txheeb xyuas cov qauv ntawm DNA Xyoo 1953, kos duab ntawm Maurice Wilkins, Rosalind Franklin thiab lwm tus.
Ib sab ntawm no, Francis Crick nrhiav tau dab tsi?
DNA
Tsis tas li ntawd, Crick thiab Watson nrhiav DNA li cas? Watson thiab Crick qhia tias txhua strand ntawm lub DNA molecule yog tus qauv rau lwm tus. Thaum lub sij hawm cell faib ob strands sib cais thiab nyob rau hauv txhua strand ib tug tshiab "lwm ib nrab" yog tsim, ib yam li ib tug ua ntej. Los ntawm 1962, thaum Watson , Crick , thiab Wilkins yeej qhov Nobel nqi zog rau physiology / tshuaj, Franklin tau tuag.
Kuj kom paub, Francis Crick pab txhawb DNA dab tsi?
Francis Harry Compton Crick OM FRS (8 Lub Rau Hli 1916 - 28 Lub Xya Hli 2004) yog tus kws tshawb fawb British molecular biologist, biophysicist, thiab neuroscientist. Nyob rau xyoo 1953, nws tau sau nrog James Watson cov ntawv qhia kev qhia txog ob lub helix qauv ntawm DNA molecule.
Leej twg tsim DNA?
James Watson thiab Francis Crick qhia thawj qhov tseeb ob-helix qauv ntawm DNA qauv. Kev sim Meselson-Stahl tau lees paub cov txheej txheem rov ua dua raws li tau hais los ntawm cov qauv ob-helical. Watson, Crick , thiab Wilkins koom ua ke tau txais Nobel nqi zog hauv Physiology lossis Tshuaj.

Dab tsi yog qhov cuab yeej tsim nyog ua ntej kev tshawb xav ntawm tes yuav tsim tau?
Lub microscope yog tsim nyog ua ntej qhov kev xav ntawm tes yuav tsim. Peb tus kws tshawb fawb twg tau txais qhab nia rau cov pov thawj ncaj qha ua rau txoj kev xav ntawm tes? Matthias Schleiden, Theodor Schwann, thiab Rudolph Virchow peb yog txhua tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes
Lub chaw tsim hluav taws xob nuclear tsim tau li cas?
Nuclear fission tsim cua sov Reactors siv uranium rau nuclear roj. Cov uranium tau ua tiav rau hauv cov me me ceramic pellets thiab muab tso ua ke rau hauv cov raj hlau kaw hu ua roj rods. Lub tshav kub tsim los ntawm fission hloov cov dej mus rau hauv chav, uas tig lub turbine los tsim hluav taws xob tsis muaj carbon
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
Francis Crick pab txhawb rau kev tshawb pom DNA li cas?
Francis Crick, James Watson thiab Maurice Wilkins tau qhia txog 1962 Nobel Prize for Physiology lossis Tshuaj rau kev daws cov qauv ntawm DNA. Txoj kev xav ntawm RNA coding tau sib cav thiab sib tham, thiab xyoo 1961, Francis Crick thiab Sydney Brenner tau muab cov pov thawj caj ces uas tus lej triplet tau siv los nyeem cov khoom siv caj ces
James Watson thiab Francis Crick nyob qhov twg?
James Dewey Watson yug rau 6 Lub Plaub Hlis 1928 hauv Chicago thiab kawm hauv cov tsev kawm qib siab hauv Chicago, Indiana thiab Copenhagen. Tom qab ntawd nws tsiv mus rau Cambridge University. Watson thiab Crick ua haujlwm ua ke ntawm kev kawm txog cov qauv ntawm DNA (deoxyribonucleic acid), cov molecule uas muaj cov ntaub ntawv keeb kwm ntawm cov hlwb
