Cov plaub nitrogen hauv paus pom hauv DNA yog adenine, cytosine, guanine, thiab thymine.

Ntawm no, plaub lub hauv paus uas ua rau tib neeg DNA yog dab tsi?

DNA qauv DNA yog ua li ntawm cov molecules hu ua nucleotides. Txhua nucleotide muaj ib pawg phosphate, pawg suab thaj thiab nitrogen puag . Cov plaub hom nitrogen hauv paus yog adenine (A), thymine (T), guanine (G) thiab cytosine (C). Qhov kev txiav txim ntawm cov no hauv paus yog qhov txiav txim DNA cov cov lus qhia, los yog genetic code.

Tom qab ntawd, lo lus nug yog, dab tsi yog plaub lub hauv paus uas ua rau lub rungs ntawm DNA ntaiv? Teb thiab piav qhia: Cov rungs ntawm DNA ntaiv yog tsim los ntawm plaub lub hauv paus nitrogen. Muaj ob purines - adenine thiab guanine thiab ob pyrimidines- cytosine thiab thymine.

Tsis tas li ntawd, dab tsi yog lub hauv paus khub quizlet?

Cov ntsiab lus hauv pawg no (8) A pib khub yog ib qho ntawm khub A-T los yog G-C. Daim ntawv ceeb toom tias txhua tus pib khub muaj purine thiab pyrimidine. Cov nucleotides hauv a pib khub yog complementary uas txhais tau hais tias lawv cov duab tso cai rau lawv ua ke nrog hydrogen bonds. The A-T khub tsim ob daim ntawv cog lus hydrogen.

Dab tsi yog plaub lub hauv paus nitrogenous pom hauv RNA quizlet?

Ib tug ntawm plaub nitrogenous puag nrog rau adenine, guanine, thiab cytosine; thymine yog ua ke nrog adenine. Ib tug ntawm plaub nitrogenous puag nrog rau adenine, guanine, thiab thymine; cytosine yog ua ke nrog guanine.
