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.
