Cov lus teb yooj yim rau nws yog yog, nucleic acids yog dej-soluble Nucleic acids yog soluble tag nrho hauv dej muab qhov polar xwm. Lub tsev blocks ntawm cov tshuaj hereditary DNA thiab RNA yog nucleotides uas muaj pyrimidine los yog purine nplhaib, pentose qab zib thiab ib pawg phosphate.
YPuas nucleic acid dej soluble?
Kev sib cuam tshuam ntawm cov dej ntawm nucleic acids tsis to taub. Piv txwv li, nucleic acids yog insoluble hauv ethanol, TCA, dej txias thiab kub, thiab diluted hydrochloric acid; Tab sis lawv yog soluble hauv diluted NaOH, cawv thiab HCl.
Yuav ua li cas rau nucleic acids hauv dej?
Los ntawm kev tsim ob lub helix, DNA tau txais cov nitrogenous hauv paus (cov no yog AGTC) tawm ntawm dej thiab mus rau hauv qhov chaw uas lawv tsis tas yuav cuam tshuam nrog dej ntau. Cov lus teb yooj yooj yim yog cov nucleic acids yuav tsim ob lub helicies hauv dej (yog tias lawv tuaj yeem)thiaj li tau txais lawv qhov chaw hydrophobic ntau tawm ntawm dej.
YPuas yog nucleic acids hydrophobic lossis hydrophilic?
YPuas yog nucleic acids hydrophilic lossis hydrophobic? Vim li cas? Nucleic acids
yog hydrophilic . DNA yog soluble nyob rau hauv dej vim hais tias cov suab thaj thiab phosphate molecules uas ua rau lub DNA caj qaum yog hydrophilic.
3 nucleic acids piv txwv yog dab tsi?
Piv txwv ntawm Nucleic Acids
- deoxyribonucleic acid (DNA)
- Yribonucleic acid (RNA)
- messenger RNA (mRNA)
- transfer RNA (tRNA)
- ribosomal RNA (rRNA)
