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.
