Muaj ob hom nucleic acids uas yog polymers pom nyob rau hauv tag nrho cov nyob cell. Deoxyribonucleic acid (nrog rau DNA ) feem ntau pom muaj nyob rau hauv lub nucleus ntawm lub cell, thaum Ribonucleic Acid (RNA) feem ntau pom nyob rau hauv lub cytoplasm ntawm lub cell txawm hais tias nws yog feem ntau synthesized nyob rau hauv lub nucleus.
Tib neeg kuj nug, qhov twg cov nucleic acids pom hauv cov zaub mov?
Tag nrho cov nqaij, nrog rau cov nqaij nruab deg, thiab cov nqaij nruab deg muaj cov qib siab nucleic acids . Nqaij extracts thiab gravy kuj tseem ceeb heev. Ntawm no zaub mov , cov nqaij nruab deg xws li daim siab muaj cov nuclei tshaj plaws, thiab yog li ntawd siab tshaj plaws hauv nucleic acids . Conversely, cov khoom siv mis nyuj thiab txiv ntoo yog suav tias yog qis- nucleic acid zaub mov.
Ib yam li ntawd, tag nrho cov nucleic acids muaj dab tsi? Basic qauv Txhua nucleotide muaj ib tug nitrogen- muaj aromatic puag txuas rau pentose (tsib-carbon) qab zib, uas yog nyob rau hauv lem txuas mus rau ib pawg phosphate. Txhua nucleic acid muaj plaub ntawm tsib tau nitrogen- muaj hauv paus: adenine (A), guanine (G), cytosine (C), thymine (T), thiab uracil (U).
Tsis tas li ntawd, peb yuav tau txais cov nucleic acids li cas?
Lub hauv paus ntsiab lus ntawm biological nucleic acids yog cov nucleotide, txhua yam uas muaj pentose qab zib (ribose los yog deoxyribose), ib pawg phosphate, thiab nucleobase. Nucleic acids Kuj tseem tsim tawm hauv chav kuaj, los ntawm kev siv cov enzymes (DNA thiab RNA polymerases) thiab los ntawm cov khoom siv tshuaj lom neeg-theem.
Qhov twg tuaj yeem pom ob hom nucleic acids loj hauv lub cell thiab lawv lub luag haujlwm yog dab tsi?
RNA Structure thiab Function. Cov ob yam tseem ceeb ntawm nucleic acids yog deoxyribonucleic kua qaub (DNA) thiab ribonucleic kua qaub (RNA). DNA yog cov khoom siv caj ces pom nyob rau hauv tag nrho cov muaj sia nyob thiab yog pom Nyob rau hauv lub nucleus ntawm eukaryotes thiab nyob rau hauv chloroplasts thiab mitochondria.

Vim li cas nucleic acids tsis nyob rau hauv cov ntawv qhia zaub mov?
Txawm hais tias nucleic acids yog ib qho tseem ceeb macromolecule, lawv tsis nyob rau hauv cov zaub mov pyramid los yog ntawm cov khoom noj khoom haus. Qhov no yog vim lawv nyob rau hauv txhua yam peb noj uas ib zaug nyob thiab noj cov nyob los yog ib zaug muaj sia nyob tsis hloov ib yam ntawm peb genetic ntaub ntawv los yog tej zaum yuav pab tau los yog ua mob rau peb nyob rau hauv ib qho kev tshwm sim
Dab tsi yog qhov ntsuas ntsuas rau nucleic acids?
Lub (Dische) Diphenylamine Test yog siv los txiav txim seb muaj cov nucleic acids. Lub xub ntiag ntawm DNA yuav tig ib qho kev daws teeb meem xiav. Qhov ntau DNA nthuav tawm cov xim tsaus. Lwm nucleic acid, RNA, yuav tig ntsuab
Dab tsi yog atoms nyob rau hauv nucleic acids?
Cov pab pawg phosphate tso cai rau cov nucleotides sib txuas ua ke, tsim cov suab thaj-phosphate qaum ntawm nucleic acid thaum lub hauv paus nitrogenous muab cov tsiaj ntawv ntawm cov tsiaj ntawv caj dab. Cov Cheebtsam ntawm nucleic acids yog tsim los ntawm tsib lub ntsiab: carbon, hydrogen, oxygen, nitrogen, thiab phosphorous
Muaj pes tsawg hom monomers muaj nyob rau hauv nucleic acids?
tsib Ntxiv mus, muaj pes tsawg hom monomers muaj nyob rau hauv cov hmoov txhuv nplej siab? Nyob ntawd tsuas yog 1. Ib yam li ntawd, qhov sib txawv ntawm nucleic acids yog dab tsi? Ob yam tseem ceeb ntawm nucleic acids yog deoxyribonucleic acid (DNA ) thiab ribonucleic acid (RNA).
Koj pom nucleic acids nyob qhov twg hauv lub cev?
Teb thiab piav qhia: Nucleic acid muaj nyob thoob plaws hauv lub cev ntawm cov kab mob multicellular eukaryotic, nyob rau hauv uas nws muaj nyob rau hauv lub nucleus ntawm txhua lub cell hauv daim ntawv ntawm
