Nucleotides yog lub tsev thaiv ntawm RNA thiab DNA. Lawv raug tsim los ntawm 5- carbon qab zib (ribose lossis deoxyribose), pawg phosphate, thiab nitrogenous pyrimidine lossis purine puag. Cov pyrimidines yog 6 lub nplhaib nrog 2 nitrogen atoms hauv lub nplhaib.
Nucleotide muaj pes tsawg carbon suab thaj?
A nucleotide yog tsim los ntawm peb yam tshuaj lom neeg sib txawv: a tsib-carbon qab zib molecule, nucleobase-ob qho tib si ua ke hu ua nucleoside-thiab ib qho phosphate. group.
Puas nucleotides muaj 6 carbon qab zib?
DNA yog ib qho polymer. Cov monomer units ntawm DNA yog nucleotides, thiab cov polymer hu ua "polynucleotide." Txhua nucleotide muaj 5-carbon qab zib(deoxyribose), nitrogen uas muaj cov hauv paus txuas nrog qab zib, thiab pawg phosphate.
YPuas yog deoxyribose ib 6 carbon qab zib?
Deoxyribose, tseem hu ua d-2-deoxyribose, tsib-carbon qab zib cov khoom ntawm DNA (q.v.; deoxyribonucleic acid), qhov uas nws hloov nrog phosphate pawg los tsim "cov pob txha. "ntawm DNA polymer thiab khi rau nitrogenous bases.
Puas yog 3 carbon qab zib pom hauv DNA nucleotides?
Muaj tsib lub hauv paus nitrogenous; adenine, guanine, thymine, cytosine thiab uracil. Nucleotides tau koom ua ke los ntawm covalent bonds ntawm pawg phosphate ntawm ib nucleotide thiab thib peb carbon atom ntawm pentose qab zibhauv nucleotide tom ntej.
