Nucleic Acid Nucleic acid yog ib chav tseem ceeb ntawm macromolecules pom nyob rau hauv txhua lub hlwb thiab cov kab mob. … 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.
YPuas DNA yog nucleic acid lossis nucleotide?
Nucleotides yog cov units thiab cov tshuaj uas sib koom ua ke los ua nucleic acids, tshwj xeeb tshaj yog RNA thiab DNA. Thiab ob qho tib si yog cov saw ntev ntawm kev rov ua dua nucleotides.
Vim li cas DNA thiaj suav tias yog nucleic acid?
DNA tsuas yog ib hom nucleic acid xwb. Lwm hom yog RNA, mRNA, thiab tRNA. Tag nrho cov "NAs" no ua haujlwm ua ke los pab cov hlwb rov ua dua thiab tsim cov proteins. … Lawv hu ua nucleic acids vim cov kws tshawb fawb thawj zaug pom lawv nyob rau hauv lub nucleus ntawm cov hlwb.
YPuas RNA yog nucleic acid?
RNA, lossis ribonucleic acid, yog a nucleic acid uas zoo ib yam hauv cov qauv rau DNA tab sis txawv ntawm txoj kev hloov maj mam. Lub xovtooj ntawm tes siv RNA rau ntau txoj haujlwm sib txawv, ib qho hu ua messenger RNA, lossis mRNA.
4 hom nucleic acids yog dab tsi?
Lub sijhawm xyoo 1920-45, ib txwm tshwm sim nucleic acid polymers ( DNA thiab RNA) tau xav tias tsuas muaj plaub canonical nucleosides (ribo-los yog deoxy-derivatives): adenosine, cytosine, guanosine, thiab uridine lossis thymidine.
