DNA cov qauv raug thauj mus rau hauv qhov dej ntawm tsis zoo electrode kawg ntawm gel . Lub hwj chim tau qhib thiab DNA tawg tawg nkag mus gel (mus rau zoo electrode ). Cov tawg loj tshaj plaws yog nyob ze rau saum lub gel ( tsis zoo electrode , qhov twg lawv pib), thiab cov seem me tshaj yog nyob ze ntawm hauv qab ( zoo electrode ).

Ib sab ntawm qhov no, cov cim zoo thiab qhov tsis zoo sawv cev li cas thiab vim li cas qhov zoo tso rau hauv qab ntawm gel?

Ib qho hluav taws xob tam sim no yog siv thoob plaws lub gel yog li ntawd ib kawg ntawm lub gel muaj ib zoo nqi thiab lwm kawg muaj ib tsis zoo nqi. Molecules tsiv mus rau qhov opposite nqi. Ib qho molecule nrog a tsis zoo nqi yuav yog li ntawd yuav rub mus rau lub zoo kawg (opposites nyiam!).

Tsis tas li ntawd, puas yog qhov zoo lossis qhov tsis zoo electrode ze tshaj plaws rau cov qhov dej? Thaum siv hluav taws xob tam sim no, pom tias qhov tsis zoo electrode yog nyob ze ntawm lub qhov dej , thiab cov zoo electrode yog nyob deb tshaj ntawm lub qhov dej.

Nyob rau hauv kev hwm rau qhov no, vim li cas cov gel tau teeb tsa los ntawm qhov tsis zoo electrode mus rau qhov zoo?

Cov tsis zoo tsub rau ntawm qab zib-phosphate qaum ntawm DNA polymers ua rau lawv tsiv mus nyob rau hauv zoo electrode thaum tso hauv ib qho hluav taws xob teb. Cov pores txwv kev txav ntawm DNA thiab tsim ib puag ncig hauv uas txhua tus neeg DNA feem ntawm qhov kev txav mus los txawv raws li nws qhov ntev.

Lub hom phiaj ntawm qhov dej hauv cov gel yog dab tsi?

Cov lub qhov dej pab lub lub hom phiaj ntawm inserting DNA sib tov rau hauv matrix ntawm lub gel tsis ua puas rau gel . Cov qauv peb thauj khoom rau hauv lub qhov dej muaj peb yam: dej, loading dye, thiab DNA.

Qhov twg hauv qab no zoo tshaj plaws sawv cev rau qhov sib npaug molecular rau cov tshuaj tiv thaiv ntawm aqueous ammonia nrog sulfuric acid?

Nqe Lus Nug: Qhov Sib npaug Sib npaug rau Kev Ua Haujlwm Ntawm Aqueous Sulfuric Acid Nrog Aqueous Ammonia yog 2NH3 (aq) + H2SO4 (aq) --> (NH4) 2SO4 (aq) A

Dab tsi ntawm cov khoom hauv qab no ntawm dej tso cai rau kab taug kev ntawm dej?

Nws tsis yog tsuas yog dej-cua saum npoo nro uas tso cai rau cov kab taug kev hauv dej. Nws yog kev sib xyaw ua ke ntawm ob txhais ceg tsis raug wetted thiab nto nro. Ob txhais ceg ntawm dej striders yog hydrophobic. Cov dej molecules muaj zog heev attracted rau ib leeg

Yuav ua li cas tshwm sim rau lub parallel phaj capacitor thaum lub dielectric muab tso rau ntawm daim hlau?

Thaum cov khoom siv dielectric tau qhia nruab nrab ntawm daim hlau Thiab thaum cov khoom siv dielectric muab tso rau nruab nrab ntawm daim hlau ntawm cov paib sib npaug ntawm cov phaj capacitor ces vim polarization ntawm cov nqi ntawm ob sab ntawm dielectric, nws tsim hluav taws xob teb ntawm nws tus kheej uas ua nyob rau hauv ib qho kev taw qhia opposite. rau lub teb vim

Vim li cas lawv muab calcium chloride tso rau hauv dej haus?

Nws feem ntau yog siv los ua ib qho electrolyte hauv cov dej haus kis las thiab lwm yam dej haus, suav nrog cov dej hauv lub raj mis. Cov saj qab ntsev heev ntawm calcium chloride yog siv los ua cov kua txiv hmab txiv ntoo uas tsis ua rau cov zaub mov muaj sodium ntau ntxiv
