Cytosine, nitrogenous puag tau los ntawm pyrimidine uas tshwm sim hauv nucleic acids, cov tshuaj tswj hwm ntawm txhua lub hlwb, thiab hauv qee cov coenzymes, cov tshuaj uas ua ke nrog Cov enzymes hauv tshuaj lom neeg hauv lub cev.

YPuas yog cytosine yog purine lossis pyrimidine?

Vim lawv cov qauv zoo sib xws, peb feem ntau xa cov cuaj-tus tswv cuab ob lub nplhaib adenine thiab guanine ua purines, thiab rau-tus tswv cuab ib lub nplhaib thymine, uracil, thiab cytosine yog pyrimidines.

YPuas yog cytosine piv txwv ntawm pyrimidine?

YCytosine yog

a pyrimidine nucleobase nrog cov tshuaj formula C 4H5N 3O. … Nws kuj tseem tuaj yeem pom muaj nyob hauv nucleoside (nucleobase + qab zib deoxyribose lossis ribose) thiab nucleotide (nucleoside nrog phosphate pawg). Hauv DNA thiab RNA, cytosine phim nrog guanine ua peb daim ntawv cog lus hydrogen.

YPuas yog thymine yog pyrimidine?

Thymine yog ib qho pyrimidine(molecular formula, C5H6N2O2) pom feem ntau hauv DNA hauv daim ntawv ntawm deoxynucleotidyl residue, ua ke nrog adenine.

Puas yog cytosine thiab guanine pyrimidines?

Cov purines hauv DNA yog adenine thiab guanine, tib yam li hauv RNA. Cov pyrimidines hauv DNA yog cytosine thiab thymine; Hauv RNA, lawv yog cytosine thiab uracil. Purines loj dua pyrimidines vim tias lawv muaj ob lub nplhaib qauv thaum pyrimidines tsuas muaj ib lub nplhaib xwb.
