Lawv yog tsim los ntawm nucleotides, uas yog cov monomers ua los ntawm peb yam: ib tug 5-carbon qab zib, ib pawg phosphate thiab ib tug nitrogenous puag. Yog hais tias cov suab thaj yog ib tug compound ribose, lub polymer yog RNA (ribonucleic kua qaub ); Yog hais tias cov piam thaj tau muab los ntawm ribose li deoxyribose, lub polymer yog DNA (deoxyribonucleic kua qaub ).
Yog li ntawd, dab tsi yog cov polymers ntawm nucleic acids?
Nucleic acids yog cov polymers ntawm tus kheej nucleotide cov monomers . Txhua nucleotide yog tsim los ntawm peb ntu: 5-carbon qab zib, phosphate pawg, thiab nitrogenous puag. Tsuas yog ob 5-carbon suab thaj muaj nyob rau hauv qhov: ribose thiab deoxyribose.
Ib sab saum toj, dab tsi yog monomers thiab polymers ntawm nucleic acids? Nucleic Acids - polymers yog DNA thiab RNA; cov monomers yog nucleotides, uas nyob rau hauv lem muaj ib tug nitrogenous puag, pentose qab zib, thiab phosphate pawg. Carbohydrates - polymers yog polysaccharides thiab disaccharides *; cov monomers yog monosaccharides (cov suab thaj yooj yim)
Kuj Paub, dab tsi yog polymer ntawm nucleotide?
DNA yog a polymer . Cov monomer units ntawm DNA yog nucleotides , thiab cov polymer yog hu ua "polynucleotide." Txhua nucleotide muaj 5-carbon qab zib (deoxyribose), nitrogen uas muaj lub hauv paus txuas nrog qab zib, thiab phosphate pawg.
Dab tsi yog monomer ntawm nucleic acid hu ua?
Tag nrho nucleic acids yog tsim los ntawm tib lub tsev blocks ( cov monomers ). Chemists hu ua cov monomers "Nucleotides." Cov tsib daim yog uracil, cytosine, thymine, adenine, thiab guanine. Txawm hais tias koj nyob hauv chav kawm txuj ci dab tsi, koj yuav hnov txog ATCG thaum saib DNA.

Cov qauv thiab kev ua haujlwm ntawm nucleic acids yog dab tsi?
Nucleic acids yog macromolecules uas khaws cov ntaub ntawv caj ces thiab ua kom muaj protein ntau. Nucleic acids muaj xws li DNA thiab RNA. Cov molecules no yog tsim los ntawm ntev strands ntawm nucleotides. Nucleotides yog tsim los ntawm nitrogenous puag, tsib-carbon qab zib, thiab phosphate pawg
Dab tsi yog qee qhov haujlwm ntawm nucleic acids?
Lub luag haujlwm ntawm nucleic acids yuav tsum ua nrog kev khaws cia thiab nthuav tawm cov ntaub ntawv ntawm caj ces. Deoxyribonucleic acid (DNA) encodes cov ntaub ntawv uas lub cell xav tau los ua cov proteins. Ib hom nucleic acid, hu ua ribonucleic acid (RNA), tuaj nyob rau hauv ntau hom molecular uas koom nrog cov protein synthesis
Lub luag haujlwm ntawm nucleic acids hauv cov nroj tsuag yog dab tsi?
Lub luag haujlwm ntawm Nucleic Acids nyob rau hauv Dab Tsi? Nucleic acids yog cov molecules loj uas nqa tons ntawm cov ntsiab lus me me: tag nrho cov ntaub ntawv caj ces. Nucleic acids muaj nyob hauv txhua yam muaj sia - nroj tsuag, tsiaj txhu, kab mob, kab mob, fungi - uas siv thiab hloov lub zog
Lub luag haujlwm ntawm nucleic acids yog dab tsi?
Cov haujlwm ntawm nucleic acids yuav tsum ua nrog kev khaws cia thiab nthuav tawm cov ntaub ntawv ntawm caj ces. Deoxyribonucleicacid (DNA) encodes cov ntaub ntawv uas lub cell xav tau los ua cov protein. Ib hom nucleic acid, hu ua ribonucleicacid (RNA), los ntawm ntau hom molecular uas koom nrog hauv kev tsim cov protein
