Nucleotides tau txais hauv kev noj haus thiab tseem synthesized los ntawm cov as-ham los ntawm lub siabNucleotides yog tsim los ntawm peb subunit molecules: nucleobase, tsib-carbon qab zib (ribose los yog deoxyribose), thiab ib pawg phosphate uas muaj ib txog peb phosphates.
Nucleotides tsim li cas?
Nucleotides yog monomeric units ntawm nucleic acids. Lub nucleotide yog tsim los ntawm cov carbohydrate residue txuas nrog lub hauv paus heterocyclic los ntawm β-D-glycosidic daim ntawv cog lus thiab mus rau pawg phosphate ntawm C-5' (cov tshuaj muaj cov phosphate pawg ntawm C- 3' kuj paub).
Nucleic acids nyob rau hauv lub cell nyob qhov twg?
Lawv hu ua nucleic acids vim tias cov kws tshawb fawb thawj zaug pom lawv hauv cov nucleus ntawm cov hlwb. Tam sim no peb muaj cov cuab yeej zoo dua, cov nucleic acids tau pom hauv mitochondria, chloroplasts, thiab cov hlwb uas tsis muaj nucleus, xws li cov kab mob thiab cov kab mob.
YPuas yog nucleotides tsim nyob rau hauv nucleus?
Lub nucleus paub tias muaj ob hom nucleic acid, deoxyribonucleic acid, thiab ribonucleic acid. … Ob lub enzymes uas tau pom nyob rau hauv cov nucleus cais yog DNA polymerase uas catalyzes cov synthesis ntawm nucleotide polymers los ua DNA thiab RNA polymerase, uas ua tib yam rau RNA.
3 nucleic acids piv txwv yog dab tsi?
Piv txwv ntawm Nucleic Acids
- deoxyribonucleic acid (DNA)
- Yribonucleic acid (RNA)
- messenger RNA (mRNA)
- transfer RNA (tRNA)
- ribosomal RNA (rRNA)
