Cov hauv paus yog "cov ntawv" uas sau tawm cov kab mob caj ces. … Nyob rau hauv lub hauv paus khub, adenine ib txwm ua khub nrog thymine, thiab guanine ib txwm ua khub nrog cytosine.
Vim li cas adenine tsis ua khub nrog guanine?
Kev ua khub hauv DNA yog qhov tshwj xeeb heev- adenine tsuas yog ua khub nrog thymine thiab ib yam nkaus, guanine tsuas yog khub nrog cytosine. Qhov no yog vim a purine tuaj yeem ua khub nrog pyrimidine(piv txwv li tsis muaj purine-purine lossis pyrimidine-pyrimidine puag khub tuaj yeem tshwm sim).
Yuav ua li cas yog adenine khi nrog guanine?
Koj pom, cytosine tuaj yeem tsim peb daim ntawv cog lus hydrogen nrog guanine, thiab adenine tuaj yeem 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 kev sib koom ua ke hauv paus vim tias txhua lub hauv paus tuaj yeem sib cog lus nrog tus khub tshwj xeeb.
Adenine ua khub nrog dab tsi?
Raws li cov xwm txheej ib txwm muaj, cov nitrogen-muaj cov hauv paus adenine (A) thiab thymine (T) khub ua ke, thiab cytosine (C) thiab guanine (G) ua ke. Kev khi ntawm cov khub hauv paus no ua cov qauv ntawm DNA.
Puas guanine khub nrog nws tus kheej?
Plaub lub hauv paus nitrogenous yog A, T, C, thiab G. Lawv sawv cev rau adenine, thymine, cytosine, thiab guanine. Plaub lub hauv paus sib txawv ua ke nyob rau hauv ib txoj kev hu ua complementary pairing. Adenine ib txwm ua khub nrog thymine, thiab cytosine ib txwm ua khub nrog guanine.
