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.

Koj puas tuaj yeem tawm hauv paus thaum lub sijhawm ua haujlwm?
Koj puas tuaj yeem tawm hauv paus thaum AIT? Tawm hauv paus thaum lub sij hawm AIT tsis tso cai kom txog thaum ntxiv rau hauv AIT kev cob qhia. Thaum AIT cov tub rog yuav nyob rau theem sib txawv. Theem IV muaj tsawg txoj cai thiab kav ntev li 3-4 lub lis piam.
Peb lub hauv paus pib thaum twg?
Peb Lub Ntsiab Cai ntawm Lub Siab, Kev Ncos thiab Kev Xav tau thawj zaug los ntawm Sydney Banks, tus kws qhia ntawv qib 9, yug hauv Scotland, nyob hauv British Columbia, Canada thaum ntxov 1970s. Peb Txoj Cai Kev nkag siab qee zaum hu ua Kev Noj Qab Haus Huv yav dhau los.
Lub hauv paus ntawm lub plawv dhia hauv fetal yog dab tsi?
Ib txwm pib lub plawv dhia hauv plab (FHR), qhia ntawm 135 neeg ntaus ib feeb (bpm). Lub hauv paus tus nqi yog li ntawm 110 txog 160 bpm rau 10 feeb ntu thiab ntev ≥ 2 feeb. Tsis suav nrog kev hloov pauv raws sijhawm thiab ntu ntu, cim qhov sib txawv, thiab ntu txawv ntawm ≥ 25 bpm.
Kuv puas tuaj yeem tsim lub hauv paus hauv qab kuv lub tsev?
Tsim lub hauv paus hauv qab muaj tsev nyob feem ntau yog ua tau, txawm tias qee yam yuav tsum tau ua kom ntseeg tau tias txoj haujlwm no ua tiav. Kev tsiv tsev thiab tsim cov hauv qab daus tshiab yog cov haujlwm nyuaj uas xav tau cov kws tshaj lij, cov neeg ua haujlwm muaj ntawv tso cai.
