DNA technology yog qhov chaw zoo siab hnub no. Qhov no yog kev kawm thiab kev siv cov khoom siv caj ces, thiab cov kws tshawb fawb tau siv DNA technology rau ntau lub hom phiaj thiab cov khoom. Ib feem tseem ceeb ntawm DNA technology yog cloning, uas yog tus txheej txheem ntawm ua ntau yam, zoo tib yam luam ntawm ib tug noob.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog piv txwv ntawm DNA thev naus laus zis?
Piv txwv ntawm DNA technologies
- DNA cloning. Hauv DNA cloning, cov kws tshawb fawb "clone" - ua ntau cov ntawv luam ntawm - DNA feem ntawm kev txaus siab, xws li cov noob.
- Polymerase chain reaction (PCR).
- Gel electrophoresis.
- DNA sequence.
Dab tsi yog cov txheej txheem ntawm recombinant DNA technology? Feem ntau, a recombinant DNA technology muaj tsib kauj ruam: (1) txiav qhov xav tau DNA los ntawm qhov chaw txwv, (2) nthuav cov noob luam los ntawm PCR, (3) ntxig cov noob rau hauv cov vectors, (4) hloov cov vectors rau hauv lub cev, thiab (5) tau txais cov khoom ntawm recombinant noob (Fig.
Ua li no, txhais li cas ntawm DNA technology?
DNA technology , recombinant: Cov txheej txheem siv los koom ua ke (recombine) DNA ntu. Nyob rau hauv tej yam kev mob, ib tug recombinant DNA molecule tuaj yeem nkag mus rau hauv lub xovtooj ntawm tes thiab rov ua dua nyob rau ntawd, autonomously (ntawm nws tus kheej) lossis tom qab nws tau ua ke rau hauv chromosome.
DNA technology siv li cas hauv kev ua liaj ua teb?
DNA thiab Ua liaj ua teb . DNA technology kuj tau siv txhawm rau txhim kho cov nroj tsuag tiv thaiv kab mob los ntawm kev tsim kho cov nroj tsuag kom tsim cov kab mob kis kab mob. Tsis tas li ntawd, cov noob rau cov tshuaj tua kab tau los ntawm cov kab mob tau muab tso rau hauv cov nroj tsuag kom cov nroj tsuag tiv taus kab ntsig thiab lwm yam kab tsuag.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
