Cytosine : Cytosine yog pyrimidine puag uas yog ib qho tseem ceeb ntawm RNA thiab DNA. Thymine : Thymine yog pyrimidine puag, uas yog khub nrog adenine nyob rau hauv doublestranded DNA. Nyob. Cytosine : Cytosine tshwm sim hauv DNA thiab RNA. Thymine : Thymine tsuas yog tshwm sim hauv DNA.

Ua li no, qhov txawv ntawm cytosine thiab thymine yog dab tsi?

Tus yuam sij Qhov sib txawv ntawm cytosine thiab thymine yog tias cytosine yog pyrimidine puag pom nyob rau hauv ob qho tib si DNA thiab RNA thiab ua ke nrog guanine los ntawm peb hydrogen bonds thaum thymine yog lub hauv paus pyrimidine pom tsuas yog hauv DNA thiab ua ke nrog adenine los ntawm ob daim ntawv cog lus hydrogen.

Ib yam li ntawd, kev sib raug zoo ntawm thymine thiab cytosine yog dab tsi? Chemistry ntawm cov nitrogenous hauv paus yog tiag tiag tus yuam sij rau txoj haujlwm ntawm DNA. Nws tso cai rau ib yam dab tsi hu ua complementary base pairing. 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.

Puas yog thymine thiab cytosine pyrimidines?

Cov pyrimidines ua hauv DNA yog cytosine thiab thymine ; hauv RNA, lawv yog cytosine thiab uracil. Purines loj dua pyrimidines ua vim lawv muaj ob-ntiv nplhaib qauv thaum pyrimidines ua tsuas muaj ib lub nplhaib xwb.

cytosine siv rau dab tsi?

Cytosine yog ib qho ntawm cov nitrogenous hauv paus hauv DNA thiab RNA. Nws muaj ib lub nplhaib, yog li nws yog pyrimidine, thiab nws ua rau peb hydrogen bonds, ua nws tus khub zoo tshaj plaws rau guanine. Nws tuaj yeem hloov kho, ntawm lub hom phiaj lossis los ntawm kev sib tsoo, ua rau nws daim npav qus ntawm cov hauv paus, thiab tus neeg ua si tseem ceeb hauv epigenetics.
