Cov nucleotides hauv a pib khub yog ntxiv uas txhais tau tias lawv cov duab tso cai rau lawv sib raug zoo ua ke nrog hydrogen bonds. The A-T khub tsim ob daim ntawv cog lus hydrogen. Qhov C-G khub daim ntawv peb. Qhov sib txuas ntawm hydrogen cov hauv paus ntxiv tuav ob txoj hlua DNA ua ke.

Ib yam li ntawd, complementary base pairing yog dab tsi?

Complementary puag khub yog qhov tshwm sim nyob rau hauv DNA guanine ib txwm hydrogen bonds rau cytosine thiab adenine ib txwm khi rau thymine. Kev sib cog lus ntawm guanine thiab cytosine sib koom peb daim ntawv cog lus hydrogen piv rau A-T daim ntawv cog lus uas ib txwm muab ob daim ntawv cog lus hydrogen.

Ib sab saum toj no, lub hauv paus khub ua haujlwm li cas? Cov nitrogenous hauv paus taw tes rau sab hauv ntawm tus ntaiv thiab daim ntawv khub nrog hauv paus ntawm lwm sab, zoo li rungs. Txhua base khub yog tsim los ntawm ob qhov sib ntxiv nucleotides (purine nrog pyrimidine) ua ke los ntawm hydrogen bonds. Cov puag khub hauv DNA yog adenine nrog thymine thiab cytosine nrog guanine.

Ntxiv mus, yog vim li cas complementary base pairing tshwm sim?

Complementary Base Pairing Koj pom, cytosine ua tau tsim peb hydrogen bonds nrog guanine, thiab adenine ua tau tsim ob daim ntawv cog lus hydrogen nrog thymine. Los yog, yooj yim dua, C daim ntawv cog lus nrog G thiab A daim ntawv cog lus nrog T. Nws yog hu ua complementary puag khub vim cwb puag tau tsuas yog daim ntawv cog lus nrog ib qho tshwj xeeb puag tus khub.

Lub hauv paus ua guanine ua ke nrog dab tsi?

cytosine
