Xam cov tshuaj formula
| Puag | Formula (DNA) | Formula ( RNA ) |
|---|---|---|
| G | C10H12O6N5P | C10H12O7N5P |
| C | C9H12O6N3P | C9H12O7N3P |
| T | C10H13O7N2P | (C10H13O8N2P) |
| U | (C9H11O7N2P) | C9H11O8N2P |
Ua kom pom qhov no, DNA tshuaj lom neeg yog dab tsi?
Deoxyribonucleic acid ( DNA ) yog ib tug molecule uas encodes ib tug kab mob lub genetic blueprint. DNA yog ib tug linear molecule tsim los ntawm plaub hom me me tshuaj molecules hu ua nucleotide bases: adenine (A), cytosine (C), guanine (G), thiab thymine (T). Qhov kev txiav txim ntawm cov hauv paus no yog hu ua DNA ib ntus.
Ib yam li ntawd, 3 hom DNA yog dab tsi? Peb loj cov qauv ntawm DNA yog ob leeg stranded thiab kev cob cog rua los ntawm kev sib cuam tshuam ntawm complementary puag khub. Cov no yog cov ntsiab lus A-daim ntawv, B-daim ntawv, thiab Z-daim ntawv DNA.
Xav txog qhov no, cov ntsiab lus dab tsi ua rau DNA?
Cov phosphate pab pawg tso cai rau nucleotides 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 phosphorus.
Puas yog DNA yog molecule lossis ib qho kev sib txuas?
ScienceDaily hais tias "Ib qho tshuaj sib xyaw ua ke yog cov tshuaj lom neeg uas muaj ob lossis ntau qhov sib txawv ntawm cov tshuaj sib xyaw ua ke, nrog rau qhov sib piv ruaj khov txiav txim siab qhov muaj pes tsawg leeg." DNA yog ib tug ntev molecule uas yog tsim los ntawm qab zib , phosphates, thiab nitrogenous bases (ib chav tsev, hu ua nucleotide, muaj ib qho ntawm

Cov ntaub ntawv dab tsi ua rau cov ntawv sau npe hauv cov tshuaj formula muab?
Cov ntawv lossis cov ntawv uas sawv cev rau lub ntsiab lus hu ua nws lub cim atomic. Cov lej tshwm sim raws li cov ntawv sau npe hauv cov qauv tshuaj qhia txog tus lej ntawm atoms ntawm lub caij tam sim ua ntej subscript. Yog tias tsis muaj subscript tshwm sim, ib qho atom ntawm lub ntsiab yog tam sim no
Dab tsi yog cov nyhuv tshuaj ntawm hluav taws xob muab qee qhov piv txwv ntawm cov nyhuv tshuaj?
Ib qho piv txwv ntawm cov tshuaj muaj zog hauv cov hluav taws xob tam sim no yog electroplating. Hauv cov txheej txheem no, muaj cov kua dej uas muaj hluav taws xob dhau mus. qhov no yog ib qho piv txwv ntawm kev siv tshuaj lom neeg hauv hluav taws xob tam sim no
Lub npe rau ib yam khoom tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj yog dab tsi?
Cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas cov atoms tam sim no nyob rau hauv cov tshuaj pib rov ua kom muab cov tshuaj sib xyaw tshiab tam sim no hauv cov tshuaj tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
