Guanine (G) hauv DNA yog ib-rau-ib txuas rau cytosine (C), yog li ntawd kuj ua rau 10%. Tom qab ntawd muaj 80% tshuav rau lwm tus ib-rau-ib khub: Thymine (T) thiab adenine (A). Yog li 40% T thiab 40% A.
pes tsawg feem pua yog guanine?
Vim tias cytosine thiab guanine muaj nyob rau hauv qhov sib npaug, peb tuaj yeem faib lawv cov lej los ntawm 2. Qhov kawg muaj pes tsawg leeg yog 22% adenine, 22% thymine, 28% cytosine, thiab 28% guanine.
Dab tsi yog feem pua ntawm guanine hauv cov qauv DNA uas muaj 20% thymine?
A ob-stranded DNA molecule nrog 20% thymine yuav muaj 30% guanine.
Dab tsi yog qhov piv ntawm guanine rau thymine hauv DNA?
Chargaff txoj cai hais tias DNA los ntawm txhua hom kab mob yuav tsum muaj 1:1 stoichiometric piv ntawm purine thiab pyrimidine hauv paus (piv txwv li, A + G=T + C) thiab, tshwj xeeb tshaj yog, tus nqi ntawm guanine yuav tsum sib npaug rau cytosine thiab tus nqi ntawm adenine yuav tsum sib npaug rau thymine.
% ntawm guanine yog dab tsi yog qhov feem pua ntawm adenine yog 20%?
Vim adenine yog 20%, ces thymine yog 20% thiab. Tag nrho ob qho tib si yog 40%. Los ntawm 100 tseem tshuav 60% uas muab faib sib npaug ntawm guanine thiab cytosine, yog li txhua tus yog 30%.
