Ib tug telocentric chromosome yog a chromosome uas nws centromere nyob ntawm ib kawgLub centromere nyob ze heev rau qhov kawg ntawm chromosome uas lub caj npab yuav tsis, los yog NW nyuam qhuav, pom. Ib chromosome uas muaj ib tug centromere ze rau qhov kawg tshaj qhov chaw yog piav raws li subtelocentric.
Kev ua haujlwm ntawm Telocentric chromosome yog dab tsi?
maderaspatensis rau 6 khub ntawm telocentric chromosomes qhia kev sib cais tsis tu ncua thaum lub sijhawm meiosis Qhov kawg ntawm cov chromosomes zoo li tus pas nrig pom tau pom ntawm tus ncej thaum lub sij hawm mitotic anaphase. Cov no yog qhov qhia tau hais tias muaj kev ua haujlwm centromere ntawm lawv lub davhlau ya nyob twg.
Telocentric yog dab tsi?
: muaj lub centromere terminally situated kom muaj tsuas yog ib chromosomal caj npab ib telocentric chromosome.
Telocentric thiab Metacentric chromosome yog dab tsi?
Chromosomes nrog centromeres positioned visibly off-center hu ua submetacentric. Acrocentric thiab telocentric chromosomes muaj centromeres nyob ze heev thiab tom kawg ntawm chromosome, feem. Nyob rau hauv cov ntaub ntawv ntawm telocentrics, lub centromere yog qhov kawg ntawm chromosome nyob ib sab ntawm lub telomere.
Qhov txawv ntawm Acrocentric thiab Telocentric yog dab tsi?
A telocentric thiab acrocentric chromosome txawv ntawm ib leeg raws li txoj hauj lwm ntawm lub centromereCov telocentric chromosomes muaj nyob rau ntawm qhov kawg lossis qhov kawg ntawm chromosomes thaum lub acrocentric chromosome yog tam sim no nruab nrab ntawm qhov chaw nruab nrab thiab lub davhlau ya nyob twg, uas yog nyob rau ntawm txoj haujlwm sub-terminal.
