Uracil yog ib qho ntawm plaub lub hauv paus nitrogenous pom hauv RNA molecule: uracil thiab cytosine (los ntawm pyrimidine) thiab adenine thiab guanine (muab los ntawm purine). … Deoxyribonucleic acid (DNA) kuj muaj txhua yam ntawm cov nitrogenous hauv paus, tshwj tsis yog tias thymine yog hloov rau uracil.
Puas DNA muaj uracil?
Uracil yog nucleotide, zoo li adenine, guanine, thymine, thiab cytosine, uas yog lub tsev thaiv DNA, tshwj tsis yog uracil hloov thymine hauv RNA. Yog li uracil yog nucleotide uas pom yuav luag tshwj xeeb hauv RNA. Lawrence C.
Puas muaj nitrogenous puag hauv DNA?
DNA yog ib qho molecule ntev, ua los ntawm ntau lub me me. Ua kom DNA molecule koj xav tau: nitrogenous bases-muaj plaub ntawm no: adenine (A), thymine (T), cytosine (C), guanine (G) carbon qab zib molecules.
DNA puag muaj dab tsi?
Thiab, txhua nucleotide yog nws tus kheej tsim los ntawm peb lub hauv paus ntsiab lus: nitrogen-muajthaj av hu ua nitrogenous puag, carbon-based qab zib molecule hu ua deoxyribose, thiab thaj tsam uas muaj phosphorus hu ua pawg phosphate txuas nrog cov piam thaj molecule (Daim duab 1).
DNA tsis muaj dab tsi?
Kev piav qhia: Bonds ntawm A-T (adenine thiab thymine) yog tuav ua ke los ntawm 2 hydrogen bonds, thaum G-C (guanine thiab cytosine) tuav ua ke los ntawm 3 hydrogen bonds. Yog li ntawd, A-TCov ntawv cog lus tsis muaj zog, thiab yuav sib cais ua ntej thaum raug kub ntxhov. DNA tsis muaj uracil.
