James Dewey Watson yog yug rau 6 lub Plaub Hlis 1928 hauv Chicago thiab kawm hauv cov tsev kawm ntawv qib siab 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.
Ib yam li ntawd, James Watson thiab Francis Crick nrhiav tau tus qauv DNA li cas?
Watson thiab Crick nrhiav tshuaj qauv ntawm DNA . Hnub no xyoo 1953, Cambridge University cov kws tshawb fawb James D. Watson thiab Francis H. C. Raws li lawv qhov kev tshawb pom, DNA replicated nws tus kheej los ntawm kev sib cais rau hauv ib tug neeg strands, txhua tus uas tau los ua tus qauv rau ib tug tshiab ob chav helix.
Ib yam li ntawd, Watson thiab Crick siv pov thawj dab tsi? Franklin's crystallography muab Watson thiab Crick cov ntsiab lus tseem ceeb rau cov qauv ntawm DNA . Ib txhia ntawm cov no los ntawm lub npe nrov "daim duab 51," ib tug zoo kawg li meej thiab striking X-ray diffraction duab ntawm DNA tsim los ntawm Franklin thiab nws cov tub ntxhais kawm tiav.
Ib yam li ntawd ib tug yuav nug, Francis Crick pab txhawb rau kev tshawb pom DNA li cas?
Francis Crick , James Watson thiab Maurice Wilkins tau sib koom xyoo 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.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
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 qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Qhov Poob Crystal Qhov tsua nyob qhov twg?
Qhov tsua ntawm Crystals lossis Giant Crystal Cave (Spanish: Cueva de los cristales) yog lub qhov tsua txuas nrog Naica Mine ntawm qhov tob ntawm 300 meters (980 ft), hauv Naica, Chihuahua, Mexico. Lub chamber tseem ceeb muaj cov pob zeb loj heev selenite (gypsum, CaSO4 • 2H2O), qee qhov loj tshaj plaws ntuj siv lead ua puas tau pom
Vim li cas Watson thiab Crick kho lawv tus qauv?
Cov hauv paus muaj cov ntaub ntawv genetic sib txawv ntawm cov tsiaj thiab hauv lawv cov kev npaj hauv lub molecule. Cov pov thawj dab tsi ua rau Watson thiab Crick hloov kho lawv tus qauv? unwound, txhua strand yuav muab luam rau hauv ib tug complementary strand, ua ib tug tiag tiag replica ntawm tus thawj molecule
