Nucleotides yog cov monomers uas koom ua ke tsim cov qauv ntawm RNA thiab DNA, nrog rau muab lub zog hauv cov metabolism. (C), Guanine (G), Adenine (A), Thymine (T), thiab Uracil (U). Ib qho phosphate yog ntsev uas muaj phosphorus thiab oxygen txuas rau ib lossis ntau dua alkyl lossis aryl molecule.
Dab tsi yog ob lub monomers koom ua ke hu ua?
Ob lub monomers koom ua ke tuaj yeem ua tib yam, lossis lawv tuaj yeem sib txawv. Qhov tshwm sim ntawm lub koomhaum no yog hu ua a polymer, uas yog cov qauv tsim los ntawm ntau cov monomer rov ua dua, tsim cov saw ntev [qhov chaw: Larsen].
Nucleotides koom ua ke li cas?
Nucleotides koom ua ke los ntawm covalent bonds ntawm pawg phosphate ntawm ib nucleotide thiab thib peb carbon atom ntawm pentose qab zib nyob rau hauv lub nucleotide tom ntej Qhov no ua rau cov pob txha hloov pauv ntawm cov piam thaj - phosphate - qab zib - phosphate tag nrho raws cov saw hlau polynucleotide.
Yuav ua li cas khi nucleotides ua ke?
DNA thiab RNA yog tsim los ntawm nucleotides uas txuas rau ib leeg hauv cov saw hlau los ntawm cov khoom siv tshuaj, hu ua ester bonds, nruab nrab ntawm cov piam thaj hauv ib nucleotide thiab pawg phosphate. ntawm cov nucleotide uas nyob ib sab. Cov piam thaj yog 3' kawg, thiab phosphate yog 5' kawg ntawm txhua nucleiotide.
Dab tsi yog cov saw ntawm nucleotides uas koom ua ke los ua cov nucleic acid hu ua?
Nucleotides. DNA thiab RNA yog polymers (nyob rau hauv cov ntaub ntawv ntawm DNA, feem ntau ntev heev polymers), thiab yog tsim los ntawm monomers hu ua nucleotides. Thaum cov monomers sib xyaw ua ke, cov txiaj ntsig tau raug hu ua
a polynucleotide (poly-="ntau").
