A nucleotide yog lub hauv paus tsim thaiv ntawm nucleic acids. RNA thiab DNA yog polymers ua los ntawm cov saw ntev ntawm nucleotides. Lub nucleotide muaj cov piam thaj molecule (xws li ribose hauv RNA lossis deoxyribose hauv DNA) txuas rau pawg phosphate thiab cov hauv paus muaj nitrogen.
Tus qauv ntawm DNA hais txog nucleotides yog dab tsi?
Txhua DNA strand yog tsim los ntawm nucleotides-units ua los ntawm a qab zib (deoxyribose), ib pawg phosphate, thiab nitrogenous baseTxhua strand ntawm DNA yog polynucleotide tsim los ntawm units hu ua nucleotides. Ib tug nucleotide muaj peb yam: ib tug qab zib molecule, ib pawg phosphate, thiab ib tug nitrogenous puag.
Tus qauv ntawm RNA nucleotides yog dab tsi?
RNA muaj ribose nucleotides (nitrogenous bases ntxiv rau ribose qab zib) txuas los ntawm phosphodiester bonds, tsim cov strands ntawm qhov sib txawv. Lub hauv paus nitrogenous hauv RNA yog adenine, guanine, cytosine, thiab uracil, uas hloov thymine hauv DNA.
Dab tsi ua rau nucleotide?
A molecule muaj xws li
a nitrogen-muaj puag (adenine, guanine, thymine, lossis cytosine hauv DNA; adenine, guanine, uracil, lossis cytosine hauv RNA), phosphate pawg, thiab qab zib (deoxyribose hauv DNA; ribose hauv RNA).
Dab tsi yog qhov txawv ntawm nucleotide hauv DNA thiab RNA?
Ob leeg deoxyribonucleic acid (DNA) thiab ribonucleic acid (RNA) yog tsim los ntawm nucleotides. … DNA muaj cov suab thaj deoxyribose, thaum RNA muaj cov qab zib ribose. DNA muaj cov nitrogenous base thymine, thaum RNA muaj cov nitrogenous base uracil.
