DNA ? DNA los yog deoxyribonucleic acid yog cov khoom siv caj ces uas hloov cov ntaub ntawv caj ces los ntawm ib lub cev mus rau lawv lub caij nplooj ntoo hlav. ? Nyob rau hauv nucleus thiab mitochondria? Cov ntaub ntawv hauv DNA yog khaws cia li code (ua los ntawm A, G, C, T). ? 99% ntawm lub hauv paus yog tib yam. Qhov kev txiav txim ntawm cov hauv paus txiav txim siab tus kheej.
Ib yam li ntawd, DNA yog dab tsi?
Deoxyribonucleic acid, feem ntau hu ua DNA , yog ib tug complex molecule uas muaj tag nrho cov ntaub ntawv tsim nyog los tsim thiab tswj lub cev. Txhua yam muaj sia muaj DNA hauv lawv cov hlwb. Qhov tseeb, yuav luag txhua lub cell hauv ib lub cev muaj ntau lub cev muaj cov txheej txheem tag nrho DNA xav tau rau lub cev.
Tus qauv thiab kev ua haujlwm ntawm DNA yog dab tsi? DNA yog cov ntaub ntawv molecule. Nws khaws cov lus qhia ua rau lwm cov molecules loj, hu ua cov proteins. Cov lus qhia no tau muab khaws cia rau hauv txhua lub hlwb, faib ntawm 46 ntev cov qauv hu ua chromosomes. Cov chromosomes no yog tsim los ntawm ntau txhiab ntu luv ntawm DNA , npe gene.
Ua li no, DNA ua los ntawm dab tsi?
DNA yog ua los ntawm chemical tsev blocks hu ua nucleotides. Cov tsev blocks no yog ua los ntawm peb ntu: ib pawg phosphate, ib pawg suab thaj thiab ib qho ntawm plaub hom nitrogen hauv paus. Ua ib txoj hlua ntawm DNA , nucleotides txuas rau hauv cov saw hlau, nrog cov phosphate thiab qab zib pawg hloov pauv.
DNA Wiki yog dab tsi?
DNA , luv luv rau deoxyribonucleic acid, yog cov molecule uas muaj cov caj ces ntawm cov kab mob. Qhov no suav nrog tsiaj, nroj tsuag, protists, archaea thiab kab mob. DNA yog nyob rau hauv txhua lub cell hauv lub cev thiab qhia cov cell seb cov proteins los ua. Lawv tsis code rau cov protein ntau.

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
