Dhau li ntawm no, koj ua li cas los ua ib qho origami DNA?
- Kauj ruam 1: Fold koj nplooj ntawv. Txiav tawm tus qauv DNA.
- Kauj Ruam 2: Fold kab kab rov tav. Muab daim ntawv tso rau ntawm thawj kab rov tav.
- Kauj Ruam 3: Fold Diagonally. Tam sim no quav raws thawj kab pheeb ces kaum.
- Kauj Ruam 4: Fold Blank Dawb Sab.
- Kauj Ruam 5: Quav Sab Dawb Tom ntej.
- Kauj Ruam 6: Sau cov Folds.
- Kauj ruam 7: Cia Nws Unfurl.
Ib yam li ntawd, DNA dawb paug hu ua dab tsi? mRNA, transcription, nucleus. Sau rau hauv Tsis muaj : Nyob rau hauv protein synthesis, ib qho ntawm unwound strands ntawm DNA tsim ib qho kev sib txuas ntxiv npe blank . Cov txheej txheem no yog npe blank thiab yuav siv qhov chaw hauv lub dawb paug ntawm cov hlwb.
Tom qab ntawd, dab tsi yog chav tsev me me ntawm DNA hu ua?
nucleotide
Yuav ua li cas koj ua tus qauv DNA ib kauj ruam?
Txoj Kev 2 Ua Tus Qauv Siv Styrofoam Balls
- Sau koj cov khoom siv.
- Xim koj cov pob styrofoam.
- Pair tawm cov nitrogenous bases.
- Ua ob lub helix.
- Txuas cov nitrogenous hauv paus rau ob lub helix strands.
- Twist ob helix.

Yuav ua li cas yog daim ntawv cog lus sib txawv ntawm daim ntawv cog lus ionic?
Qhov sib txawv ntawm cov ionic thiab covalent daim ntawv cog lus yog tias covalent daim ntawv cog lus yog tsim thaum ob lub atoms sib koom electrons. Ionic bonds yog lub zog uas tuav ua ke electrostatic zog ntawm kev nyiam ntawm cov ions oppositely them. Ionic bonds muaj qhov sib txawv electronegativity ntau dua lossis sib npaug li 2
Dab tsi yog qhov txawv ntawm daim ntawv cog lus lub zog thiab daim ntawv cog lus dissociation zog?
Qhov sib txawv tseem ceeb ntawm kev sib txuas ntawm lub zog thiab lub zog bonddissociation yog tias lub zog sib txuas yog qhov nruab nrab ntawm lub zog xav tau los rhuav tshem tag nrho cov kev sib txuas ntawm tib ob hom atoms nyob rau hauv ib qho chaw sib txuas whereas daim ntawv cog lus dissociation zog yog tus nqi ntawm cov hluav taws xob xav tau los rhuav tshem ib qho kev sib koom ua ke inhomolysis
Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
