Nitrogenous puag: Ib qho molecule uas muaj nitrogen thiab muaj cov tshuaj lom neeg ntawm lub hauv paus. Lub hauv paus nitrogenous hauv DNA yog adenine (A), guanine (G), thymine (T), thiab cytosine (C). Lub hauv paus nitrogenous hauv RNA yog tib yam, nrog rau ib qho kev zam: adenine (A), guanine (G), uracil (U), thiab cytosine (C).
Nyob rau hauv nitrogen yog dab tsi?
Lub hauv paus nitrogen txuas rau the 1' (ib qho tseem ceeb) carbon atomntawm ob qho tib si deoxyribose qab zib molecule hauv DNA thiab ribose qab zib molecule hauv RNA.
Vim li cas thiaj yuav tsum muaj nitrogenous bases tswj lawv cov complementarity txhua lub sij hawm?
Vim tias lawv sib txuas ua ke, cells xav tau kwv yees li sib npaug ntawm cov purine thiab pyrimidines. Txhawm rau tswj hwm qhov sib npaug hauv lub xov tooj ntawm tes, kev tsim tawm ntawm ob qho tib si purines thiab pyrimidines yog tus kheej txwv.
nitrogenous puag tsim li cas?
Cov hauv paus no yog tsim los ntawm txawm tias ib lub nplhaib pyrimidine lossis ob lub nplhaib purine. Tom qab ntawd, qee qhov ntxiv nitrogen, hydrogen lossis oxygen molecules ntxiv rau hauv lub nplhaib yooj yim los ua cov nitrogenous hauv paus: adenine, guanine, cytosine, thymine (DNA nkaus xwb) lossis uracil (RNA nkaus xwb).
Dab tsi yog cov khoom ntawm nitrogenous puag?
Cov nitrogenous hauv paus yog Adenine (A), Cytosine (C) thiab Guanine (G) uas pom muaj nyob hauv RNA thiab DNA thiab tom qab ntawd Thymine (T) uas tsuas yog pom nyob rau hauv DNA thiab Uracil (U), uas yuav siv qhov chawntawm Thymine hauv RNA. Nitrogenous bases tuaj yeem raug cais ntxiv ua pyrimidines lossis purines.
