Cov hauv paus muaj tsis tshua muaj solubilities hauv dej, whereas cov nucleosides thiab nucleotides muaj ntau dua solubilities, vim muaj cov qab zib qab zib, los yog ntawm ob qho tib si suab thaj thiab them phosphate pawg, raws.
Puas yog nucleotides soluble hauv dej?
Cov nucleotides tus kheej yog dej solublepiv rau nucleosides uas muaj dej solubility tsawg dua. Raws li cov saw tseem ceeb yog ionized nrog nqi nws ua rau lawv ua dej soluble.
Puas nucleic acids yaj hauv dej?
Nyob rau hauv cov kua dej (kua) ntawm DNA lossis RNA, ntsev thiab ethanol tuaj yeem muab ntxiv rau hauv cov tshuaj thiab cov nucleic acid precipitates tawm ntawm cov tshuaj. … Vim li no, DNA thiab RNA tuaj yeem yooj yim yaj hauv dej.
Nucleotides cuam tshuam nrog dej li cas?
Txhawm rau txo lawv cov kev cuam tshuam nrog dej, kev sib cuam tshuam ntawm qhov chaw hydrophobic thiab dej yuav tsum raug txo kom tsawg. Nyob rau tib lub sijhawm, txhua nucleotide muaj ob pawg hydrophilic heev: ib pawg tsis zoo phosphate thiab qab zib (carbohydrate). Ob leeg form H-bonds thiab yuav cuam tshuam nrog dej.
Puas yog nucleotides polar lossis tsis polar?
Cov qab zib-phosphate caj qaum ntawm DNA yog polar, thiab yog li ntawd hydrophillic; yog li nws nyiam nyob ze rau dej. Qhov sab hauv ntawm DNA, lub hauv paus, yog txheeb ze tsis yog-polar thiab yog li hydrophobic.
