Teb thiab piav qhia: Nucleic acid muaj nyob thoob plaws hauv lub cev ntawm ib tug multicellular eukaryotic kab mob, nyob rau hauv hais tias nws muaj nyob rau hauv lub nucleus ntawm txhua cell nyob rau hauv daim ntawv ntawm

Tom qab ntawd, ib tug kuj yuav nug, qhov twg yog nucleic acids pom nyob rau hauv lub cev?

Muaj ob hom nucleic acids uas yog polymers pom nyob rau hauv tag nrho cov muaj sia nyob. Deoxyribonucleic Acid (DNA) yog pom Feem ntau nyob rau hauv lub nucleus ntawm lub cell, thaum Ribonucleic Acid (RNA) yog pom Feem ntau nyob rau hauv lub cytoplasm ntawm lub cell txawm hais tias nws yog feem ntau synthesized nyob rau hauv lub nucleus.

Ib sab saum toj no, koj yuav txheeb xyuas cov nucleic acids li cas? Tus yuam sij rau kev tshawb nrhiav qhov tshwj xeeb nucleic acid sequences yog lub hauv paus kev sib koom ua ke ntawm cov kab sib txuas ntawm RNA lossis DNA. Ntawm qhov kub thiab txias (piv txwv li, 90 txog 100 ° C), qhov sib ntxiv ntawm DNA cais (denature), yielding ib leeg-stranded molecules.

Xav txog qhov no, koj tuaj yeem nrhiav nucleic acids nyob qhov twg?

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 hauv nruab nrog cev xws li daim siab muaj cov nuclei tshaj plaws, thiab yog li ntawd siab tshaj nyob rau hauv nucleic acids . Conversely, cov khoom siv mis nyuj thiab txiv ntoo yog suav tias yog qis- nucleic acid zaub mov.

Lub luag haujlwm ntawm nucleic acids yog dab tsi?

Nucleic acid yog ib chav kawm tseem ceeb ntawm macromolecules muaj nyob hauv txhua lub hlwb thiab cov kab mob. Cov kev ua haujlwm ntawm nucleic acids yuav tsum ua nrog kev khaws cia thiab kev nthuav qhia ntawm cov ntaub ntawv caj ces. Deoxyribonucleic kua qaub (DNA) encodes cov ntaub ntawv uas lub cell xav tau los ua cov proteins.
