DNA muaj ib tus nqi tsis zoo vim o tus nqi tsis zoo ntawm nws cov phosphate tivthaiv. Phosphate txuas cov suab thaj, hu ua deoxyribose thiab los ntawm qhov twg DNA Ordeoxyribonucleic acid tau txais nws lub npe, los ua cov pob txha ntawm txhua txoj hlua ntawm DNA . Txhua qab zib yog txuas mus rau tom ntej los ntawm pawg aphosphate.
Ua raws li qhov no, vim li cas DNA thiab RNA raug them tsis zoo?
Qhov no ionization tawm ib tus nqi tsis zoo ntawm txhua pawg phosphate. Cov no nqi tso cai rau DNA strands to band rau cov protein molecules uas stabilize cov qauv, muab nucleoprotein complex. DNA muaj tus nqi tsis zoo vim muaj cov phosphate pawg. Feem ntau, hydrogen tsis qhia hauv DNA qauv.
Qhov thib ob, vim li cas cov proteins tsis zoo? Amino acids uas ua rau cov proteins muaj bepositive, tsis zoo , nruab nrab, lossis polar nyob rau hauv qhov, thiab ua ke muab a protein ntau nws zuag qhia tag nrho nqi . Thaum qis pHvalues, net nqi ntawm feem ntau cov proteins Nyob rau hauv lawv cov khoom yog zoo - nyob rau hauv cation exchangers, cov nopositively- them cov protein khi rau tsis zoo - raug them matrix.
Tsis tas li ntawd, puas yog DNA zoo lossis tsis zoo?
Phosphate pawg nyob rau hauv DNA nqa nqa tsis zoo - raug them Oxygen molecules muab cov phosphate-qab zib qaum ntawm DNA tag nrho negativecharge . Cov tsis zoo them DNA tuaj yeem rub mus rau zoo teb gel. 6.
Puas yog RNA raug them tsis zoo?
Vim DNA thiab RNA yog tsis zoo nqi molecules, lawv yuav raug rub mus rau qhov zoo raug them kawg ntawm gel.

Vim li cas thiaj tsis muaj nqi hauv tus neeg xyuas pib?
Tsis tas li ntawd, lub teb hluav taws xob hauv ib tus neeg xyuas pib yog xoom. (Qhov no, kuj, yog vim lub free txav ntawm tsub nqi. Yog hais tias muaj ib tug net hluav taws xob teb nyob rau hauv, cov nqi yuav rearrange vim hais tias ntawm nws, thiab tshem tawm nws tawm. tus thawj coj
Vim li cas kev sib raug zoo tsis zoo?
Tsawg cohesion tsis zoo vim nws qhia tias muaj cov ntsiab lus hauv chav kawm uas tsis tshua muaj kev sib koom ua ke. Modules uas nws cov ntsiab lus muaj zog thiab muaj kev sib raug zoo tiag tiag yog xav tau. Txhua txoj kev yuav tsum tau cohesive heev. Feem ntau txoj kev tsuas muaj ib txoj haujlwm los ua
Vim li cas cov nqi zoo thiab tsis zoo nyiam?
Tus nqi tsis zoo xav muab nws cov electrons los ua qhov nruab nrab yog li nws nyiam qhov zoo ntawm nws. Ntawm qhov tod tes, ib tug zoo chargere yuav tsum tau electrons los ua nruab nrab, yog li ntawd nws txav mus rau tus nqi tsis zoo
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Yuav ua li cas koj thiaj paub yog tias tus nqi tsis sib xws tsis muaj kev daws teeb meem?
Okay, yog tias qhov tseem ceeb tshaj plaws yeej ib txwm zoo lossis xoom tsis muaj txoj hauv kev uas lawv tuaj yeem tsawg dua lossis sib npaug rau tus lej tsis zoo. Yog li ntawd, tsis muaj kev daws teeb meem rau ob qho no. Hauv qhov no yog tias tus nqi tiag tiag yog qhov zoo lossis xoom ces nws yuav nco ntsoov ntau dua lossis sib npaug rau tus lej tsis zoo
