chromosome, txhawm rau nrhiav qhov ntxig ntawm DNA luv ib ntus , npe Alu , nyob rau hauv. cov ntaub so ntswg plasminogen activator ( TPA ) noob. Alu Cov ntsiab lus tau muab cais ua SINEs, lossis luv INterspersed Elements.
Tib neeg kuj nug, qhov ua haujlwm ntawm Alu yog dab tsi?
Alu cov ntsiab lus yog lub luag haujlwm rau kev tswj cov ntaub so ntswg tshwj xeeb. Lawv kuj tseem koom nrog hauv kev hloov pauv ntawm cov noob nyob ze thiab qee zaum tuaj yeem hloov pauv txoj kev gene qhia. Alu cov ntsiab lus yog retrotransposons thiab zoo li DNA luam los ntawm RNA polymerase III-encoded RNAs.
Ib tug kuj nug, koj genotype rau Alu noob yog dab tsi? Cov noob caj noob ces Keeb kwm. Qhov kev sim no tshuaj xyuas PV92, tib neeg tshwj xeeb Alu tso rau ntawm chromosome 16. Lub PV92 caj ces system tsuas muaj ob qho alleles qhia tias muaj (+) lossis tsis muaj (-) ntawm qhov Alu transposable element ntawm txhua tus khub chromosomes. Qhov no ua rau peb PV92 genotypes (++, +-, lossis --).
Xav txog qhov no, ntev npaum li cas ntawm Alu sequence?
Alu sequences yog rov ua dua DNA Kev pom zoo Alu sequences yog kwv yees li 280 bp in ntev , thiab muaj ob yam zoo sib xws, tab sis txawv monomers txuas los ntawm ib qho oligo-d(A) tract (Fig. 1). Txoj cai Alu monomer muaj 31 bp ntxig tsis tuaj ntawm sab laug monomer.
Alu PCR yog dab tsi?
Alu PCR yog ib qho kev ceev thiab yooj yim-rau-ua "DNA ntiv tes" cov txheej txheem raws li kev soj ntsuam ib txhij ntawm ntau cov genomic loci flanked los ntawm Alu Cov ntsiab lus rov ua dua, uas tso cai rau kev tshawb nrhiav cov noob caj noob ces polymorphisms thiab kev hloov pauv hauv tib neeg thiab primate genomes.

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 qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
