Duplication yog ib hom kev hloov pauv uas suav nrog kev tsim ib lossis ntau daim ntawv theej ntawm cov noob lossis thaj tsam ntawm chromosome. Gene luam tawm yog ib qho tseem ceeb mechanism uas evolution tshwm sim.
Dhau li ntawm no, dab tsi ua rau cov noob duplication?
Gene duplication (los yog chromosomal luam tawm los yog noob amplification) yog ib qho tseem ceeb mechanism los ntawm qhov tshiab caj ces Cov khoom yog tsim thaum lub sij hawm molecular evolution. Cov peev txheej ntawm gene duplications muaj xws li ectopic recombination, retrotransposition tshwm sim, aneuploidy, polyploidy, thiab replication slippage.
Dab tsi yog duplication hauv meiosis? Kev Kho Mob Txhais ntawm Chromosome luam tawm Chromosome luam tawm : Ib feem ntawm chromosome nyob rau hauv duplicate. Duplications Feem ntau tshwm sim los ntawm ib qho kev tshwm sim hu ua tsis sib npaug hla dhau (recombination) uas tshwm sim ntawm misaligned homologous chromosomes thaum lub sij hawm meiosis (kab mob cell tsim).
Ntawm no, scientific duplication yog dab tsi?
Duplication : Ib feem ntawm chromosome nyob rau hauv duplicate, ib hom kev hloov pauv (hloov) cuam tshuam nrog kev tsim ib lossis ntau daim ntawv luam ntawm ib qho DNA, suav nrog cov noob lossis txawm tias tag nrho cov chromosome.
Dab tsi yog tandem duplication hauv biology?
Tandem exon ua luam tawm yog txhais raws li luam tawm ntawm exons nyob rau hauv tib lub noob los muab nce mus rau tom ntej exon. Kev soj ntsuam tag nrho ntawm cov noob hauv Homo sapiens, Drosophila melanogaster, thiab Caenorhabditis elegans tau pom 12, 291 qhov xwm txheej ntawm tandem duplication nyob rau hauv exons nyob rau hauv tib neeg, ya, thiab cua nab.

Duplication mutation yog dab tsi?
Duplication yog ib hom kev hloov pauv uas suav nrog kev tsim ib lossis ntau daim ntawv theej ntawm cov noob lossis thaj tsam ntawm chromosome. Gene thiab chromosome duplications tshwm sim nyob rau hauv tag nrho cov kab mob, txawm hais tias lawv yog tshwj xeeb tshaj yog tseem ceeb ntawm cov nroj tsuag. Gene duplication yog ib qho tseem ceeb mechanism uas evolution tshwm sim
Dab tsi yog gene duplication hauv biology?
Gene duplication (los yog chromosomal duplication lossis gene amplification) yog ib txoj hauv kev loj los ntawm cov khoom siv caj ces tshiab tsim tawm thaum lub sij hawm molecular evolution. Nws tuaj yeem txhais tau tias yog ib qho kev sib tw ntawm thaj tsam ntawm DNA uas muaj cov noob
Dab tsi yog qhov txhais ntawm lub hauv paus hauv biology?
Txhais. npe, plural: bases. (1) (molecular biology) Lub nucleobase ntawm nucleotide koom nrog hauv kev sib koom ua ke, xws li DNA lossis RNA polymer. (2) (anatomy) Qhov qis tshaj plaws los yog hauv qab ntawm cov nroj tsuag lossis tsiaj lub cev ze tshaj rau qhov txuas. (3) (chemistry) Ib qho dej-soluble compound uas reacts nrog acid thiab cov ntaub ntawv
Dab tsi yog qeb yog marine biology nyob rau hauv?
Marine biology yog ib ceg ntawm biology. Nws muaj kev sib raug zoo nrog oceanography thiab tej zaum yuav raug suav hais tias yog ib qho kev ua haujlwm ntawm kev tshawb fawb hauv dej hiav txwv. Nws tseem suav nrog ntau lub tswv yim los ntawm ecology. Kev tshawb fawb txog kev nuv ntses thiab kev txuag dej hiav txwv tuaj yeem suav hais tias yog ib feem ntawm kev ua liaj ua teb marine biology (nrog rau kev tshawb fawb ib puag ncig)
Puas yog General Biology tib yam li cov hauv paus ntsiab lus ntawm biology?
Ob qho! Kuv xav tias nws nyob ntawm koj lub tsev kawm ntawv. Hauv kuv lub tsev kawm ntawv, cov ntsiab cai ntawm bio yog npaj rau bio majors, qhov dav dav bio yog rau lwm yam loj uas xav tau biology, uas yuav yooj yim dua
