Kev piav qhia: Nucleotides yog cov monomers ntawm ob qho tib si DNA thiab RNA . Txawm li cas los xij, nucleotides lawv tus kheej yog tsim los ntawm ntau lwm cov molecules. Ib qho nucleotide yog tsim los ntawm 5-carbon qab zib, nitrogenous puag (adenine, guanine, cytosine, thymine, lossis uracil), thiab pawg phosphate (PO3-4).
Ua raws li qhov no hauv kev xav, dab tsi yog monomers ntawm nucleotides?
Tag nrho cov nucleic acids yog tsim los ntawm tib lub tsev thaiv ( cov monomers ). Chemists hu ua cov monomers nucleotides ” Tsib daim yog uracil, cytosine, thymine, adenine, thiab guanine.
Tsis tas li ntawd, lub monomer unit ntawm DNA yog dab tsi? DNA yog polymer. Cov monomer units ntawm DNA yog nucleotides, thiab cov polymer hu ua "polynucleotide." Txhua nucleotide muaj 5-carbon qab zib (deoxyribose), nitrogen uas muaj lub hauv paus txuas nrog qab zib, thiab phosphate pawg.
Qhov sib thooj, dab tsi yog monomers ntawm DNA thiab RNA quizlet?
Cov ntsiab lus hauv pawg no (37) monomer ntawm DNA los yog RNA muaj li ntawm phosphoric acid, qab zib, (deoxyribose rau DNA thiab ribose rau RNA ) thiab nitrogen puag (ATCG rau DNA , AUCG for RNA ).
Dab tsi yog cov subunits loj ntawm cov monomers uas tsim DNA thiab RNA?
DNA thiab RNA yog ua li ntawm cov monomers hu ua nucleotides. Cov nucleotides sib xyaw ua ke ua ke ib polynucleotide, DNA los yog RNA . Txhua nucleotide yog ua li ntawm peb yam: ib nitrogenous puag, ib pentose (tsib-carbon) qab zib, thiab ib phosphate pawg (Daim duab 3.5.

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Dab tsi yog lub tsev thaiv ntawm DNA thiab RNA lub npe hu ua?
Nucleotides yog cov molecules uas muaj nucleoside thiab phosphate pawg. Lawv yog lub hauv paus tsev blocks ntawm DNA thiab RNA
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
