Qhov sib txawv tseem ceeb ntawm synteny thiab collinearity yog tias synteny yog lub cev sib koom ua ke ntawm caj ces loci ntawm tib chromosome hauv hom, thaum collinearity yog lub cev co-localization ntawm genetic loci ntawm tib chromosome hauv ntau hom kev txuag. tib order.
Synteny thiab collinearity yog ob nqe lus uas siv sib hloov hauv genomics. Ob nqe lus piav qhia txog cov qauv hauv cheeb tsam ntawm cov chromosomes hauv ntau hom. Cov kev sib txheeb ntawm cov noob caj noob ces ntawm cov taxa yog cov ntaub ntawv tseem ceeb thaum sib piv cov poj koob yawm txwv ntawm cov noob. Synteny yog hais txog kev sib koom ua ke ntawm lub cev ntawm caj ces loci ntawm tib chromosome hauv hom. Collinearity yog hais txog kev sib koom ua ke ntawm lub cev ntawm cov noob caj noob ces ntawm tib chromosome hauv ntau hom kev txuag tib yam kev txiav txim. Yog li ntawd, nws yog ib daim ntawv ntawm synteny.
Dab tsi yog Synteny?
Nyob hauv ntau hom, muaj ib txheej ntawm cov noob nyob rau tib chromosome. Thiab, qhov no lub cev co-localization ntawm cov noob ntawm tib chromosome nyob rau hauv ntau hom yog hu ua synteny. Tsis tas li ntawd, cov noob no muaj nyob ze rau ib leeg ntawm ib qho chromosome. Qhov kev txiav txim ntawm cov noob yuav tsis tas yuav zoo ib yam. Tab sis, qhov chaw ntawm cov noob nyob ze ntawm ib leeg ntawm tib chromosome tshwm sim nyob rau hauv synteny. Yog li ntawd, synteny feem ntau piav qhia txog kev faib cov noob ntawm cov chromosome. Cov qauv ntawm cov noob caj noob ces hauv zos qhia txog kev sib raug zoo ntawm ntau hom thiab lawv cov evolution. Txawm li cas los xij, synteny tuaj yeem cuam tshuam vim chromosomal rearrangements xws li translocations, inversion thiab chromosome fusion, thiab lwm yam. duplications, poob thiab tsis sib xws homologous recombination.
Daim duab 01: Synteny
Nws ntseeg tau tias txhua cov noob caj noob ces yog syntenic. Txawm li cas los xij, tsis yog tag nrho cov noob caj noob ces yuav tsum txuas. Lawv muaj cov chromosome feem ntau. Tib neeg muaj ntau cov noob caj noob ces nrog rau lwm hom tsiaj. Ntxiv mus, ntau cov cereals muaj cov noob syntenic.
Kev sib raug zoo yog dab tsi?
Collinearity yog ib daim ntawv tshwj xeeb ntawm synteny nyob rau hauv uas ib txheej ntawm noob nyob rau tib chromosome ntawm ntau hom nyob rau hauv tib txoj kev raws li nyob rau hauv cov poj koob yawm txwv hom. Yog li ntawd, yog tias muaj kev sib txawv ntawm kev sib koom ua ke, nws yuav yog ib qho kev ntseeg siab tshaj plaws phylogenetic vim collinearity piav qhia txog caj ces caj ces.
Daim duab 02: Kev sib koom ua ke
Multiway collinearity tsom xam muab cov ntaub ntawv txhim khu kev qha ntau ntxiv txog cov kab ntsig thiab lawv cov phylogeny.
Dab tsi yog qhov zoo sib xws ntawm Synteny thiab Collinearity?
- Nyob rau hauv ob qho tib si synteny thiab collinearity, ib txheej ntawm loci nyob rau hauv ob hom sib txawv nyob ntawm tib chromosome.
- Cov ntsiab lus no piav qhia txog kev sib koom ua ke ntawm lub cev ntawm caj ces loci ntawm tib chromosome.
- Collinearity yog ib daim ntawv tshwj xeeb ntawm synteny.
- Qee zaum ob nqe lus siv sib pauv hauv genomics.
- Yog tias ob thaj chaw muaj kev sib koom ua ke, lawv yog qhov sib koom ua ke.
- Lawv muaj txiaj ntsig zoo hauv kev cuam tshuam phylogeny.
Qhov txawv ntawm Synteny thiab Collinearity yog dab tsi?
Synteny thiab collinearity yog ob nqe lus uas siv sib hloov hauv genomics. Synteny yog hais txog kev sib koom ua ke ntawm lub cev ntawm ib pawg ntawm cov noob hauv tib chromosome hauv ntau hom. Collinearity yog ib hom kev sib koom ua ke uas cov noob caj noob ces sib koom ua ke hauv tib qho kev txiav txim ntawm ntau hom. Yog li ntawd, qhov no yog qhov sib txawv tseem ceeb ntawm synteny thiab collinearity.
Summary – Synteny vs Collinearity
Cov ntsiab lus synteny thiab collinearity yog hais txog ib pawg ntawm cov noob uas nyob ntawm tib chromosome hauv ntau hom. Qhov tseeb, cov noob no tau sib koom ua ke hauv tib lub chromosome hauv ntau hom. Synteny piav qhia txog lub cev co-localization ntawm cov noob caj noob ces ntawm tib chromosome nyob rau hauv ntau hom, thaum collinearity yog ib daim ntawv tshwj xeeb ntawm synteny nyob rau hauv uas cov noob yog co-localized nyob rau hauv tib txoj kev. Yog li, qhov no qhia txog qhov sib txawv ntawm synteny thiab collinearity.
