Txhua lub hauv paus ua khub nrog tus khub tshwj xeeb, tso cai rau peb los txiav txim siab lawv feem pua: adenine thiab thymine ib txwm sib npaug, thiab cytosine thiab guanine ib txwm sib npaug.
Puas guanine sib npaug rau cytosine?
DNA muaj cov pyrimidines cytosine thiab thymine, thiab cov purines adenine thiab guanine. … Chargaff nrhiav pom tias tus nqi ntawm adenine yog kwv yees li sib npaug ntawm cov thymine hauv DNA, thiab tus nqi ntawm guanine yog kwv yees li sib npaug rau cytosine.
Puas ib txwm muaj qhov sib npaug ntawm guanine thiab cytosine hauv DNA molecule Vim li cas?
Plag: ++ muaj ib txwm sib npaug tsis. guanine thiab cytosine nucleotides nyob rau hauv molecule. ++Lawv tsuas yog ua ke nrog ib leeg vim lawv cov tshuaj lom neeg..
Kev sib raug zoo ntawm guanine thiab cytosine yog dab tsi?
Guanine thiab cytosine ua ib khub ntawm nitrogenous vim lawv muaj hydrogen daim ntawv cog lus pub dawb thiab hydrogen daim ntawv cog lus ua khub nrog ib leeg hauv qhov chaw. Guanine thiab cytosine tau hais rau ua kom sib npaug.
Tus nqi ntawm cytosine sib npaug li cas?
Chargaff txoj cai hais tias DNA los ntawm txhua hom kab mob twg yuav tsum muaj 1: 1 stoichiometric piv ntawm purine thiab pyrimidine bases (piv txwv li, A + G=T + C) thiab, tshwj xeeb tshaj yog, tias tus nqi ntawmguanine yuav tsum sib npaug rau cytosine thiab tus nqi ntawm adenine yuav tsum sib npaug rau thymine.
