Qhov zoo ntawm semiconservative replication nws yog thaum lub sij hawm tus txheej txheem ntawm DNA rov ua dua muaj tsawg zaus ntawm kev ua yuam kev. Qhov tsis zoo yog tias muaj kev ua yuam kev hauv cov txheej txheem DNA rov ua dua nws tuaj yeem ua rau mob qog noj ntshav thiab lwm yam kab mob, kev yug me nyuam, thiab kev hloov pauv.
Cov lus nug tseem yog, vim li cas Semiconservative replication tseem ceeb?
Cov qhov tseem ceeb ntawm semiconservative qauv yog tias nws ua kom paub tseeb tias koj muaj cov ntawv luam ntawm DNA uas zoo ib yam rau ib leeg. Txwv tsis pub koj yuav tsis muaj peev xwm ua ib daim qauv ntawm DNA. Hom no rov ua dua ua tsaug rau DNA puag khub.
Ib yam li ntawd, vim li cas DNA replication hu ua semiconservative? DNA replication yog ib nrab - kev saib xyuas vim hais tias txhua lub helix uas yog tsim muaj ib txoj hlua ntawm lub helix los ntawm qhov uas nws tau theej. Cov rov ua dua ntawm ib tug helix tshwm sim nyob rau hauv ob tug ntxhais heliceseach uas muaj ib tug ntawm cov thawj niam txiv helicalstrands.
Ib tug kuj yuav nug, dab tsi yog qhov kev hloov pauv ntawm kev saib xyuas ib puag ncig?
semiconservative replication Txoj kev lees paub dav dav ntawm DNA rov ua dua , nyob rau hauv uas ob lub strands ntawm DNA helix cais thiab dawb nucleotides khub nrog lub hauv paus tshwm sim ntawm cov saw ib leeg los tsim ob lub DNA tshiab molecules, txhua tus muaj ib qho qub thiab ib qho tshiab synthesized strand ntawm DNA.
Yuav ua li cas yog tias DNA replication yog conservative?
DNA replicates los ntawm semi- conservativereplication , uas txhais tau hais tias ib qho strand ntawm niam txiv doublehelix yog kev txuag hauv txhua qhov tshiab DNA molecule. Tom qab plaub qhov kev rov ua dua ntxiv, lawv kuj tau ua pov thawj dispersive rov ua dua , uas qhia tias tshiab DNA muaj alternating niam txiv thiab tus ntxhais DNA.

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 zoo thiab qhov tsis zoo ntawm Mercator projection yog dab tsi?
Disadvantages: Mercator projection distorts qhov loj ntawm cov khoom raws li lub latitude nce los ntawm Equator mus rau tus ncej, qhov twg lub teev yuav infinite. Yog li, piv txwv li, Greenland thiab Antarctica tshwm sim ntau dua qhov txheeb ze rau thaj av loj nyob ze ntawm txoj kab nruab nrab tshaj li qhov lawv muaj tiag
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
