Cov qauv tshuaj ntawm Thymine thiab Cytosine me dua, thaum cov Adenine thiab Guanine loj dua. Qhov loj thiab cov qauv ntawm cov nucleotides tshwj xeeb ua rau Adenine thiab Thymine ib txwm ua ke thaum Cytosine thiab Guanine ib txwm ua ke.
guanine txawv ntawm cytosine li cas?
Adenine thiab guanine yog purine hauv paus. Cov no yog cov qauv tsim los ntawm 5-sided thiab 6-sided nplhaib. Cytosine thiab thymine yog pyrimidines uas yog cov qauv tsim los ntawm ib lub nplhaib rau rau sab. Adenine ib txwm khi rau thymine, thaum cytosine thiab guanine ib txwm khi rau ib leeg.
Nucleotides twg loj dua?
Adenine vs.
Adenine yog lub npe ntawm purine puag. Adenosine yog qhov loj dua nucleotide molecule ua los ntawm adenine, ribose lossis deoxyribose, thiab ib lossis ntau pawg phosphate.
Puas adenine thiab guanine loj dua cytosine thiab thymine?
Adenine thiab guanine yog cov molecules loj dua cytosine thiab thyminevim tias lawv muaj ob lub nplhaib hauv lawv cov qauv.
Daim ntawv cog lus twg muaj zog AT lossis GC?
Los ntawm lub hauv paus-pairing daim duab, peb pom tau hais tias cov G-C khub muaj 3 hydrogen bonds, thaum A-T khub tsuas muaj 2. Yog li ntawd, lub G-C khub yog ruaj khov dua A-T khub. Yog li, cov hlua nrog ntau G-C cov ntsiab lus muaj ntau dua hydrogen bonding, ruaj khov dua, thiab muaj kev tiv thaiv ntau dua rau denaturation.
