Thaum cov noob SRY tam sim no, nws yog feem ntau nyob ntawm X chromosome vim yog kev sib txuas ntawm X thiab Y chromosomes.
X chromosomes puas muaj SRY noob?
SRY-positive
Nyob hauv kwv yees 80 feem pua ntawm XX txiv neej, SRY noob muaj nyob rau ntawm ib qho ntawm X chromosomes. Qhov xwm txheej tshwm sim los ntawm qhov txawv txav ntawm cov khoom siv caj ces ntawm chromosomes (translocation).
Puas yog SRY noob nkaus xwb ntawm Y chromosome?
SRY yog ib ntawm plaub lub noob ntawm tib neeg Y chromosomeuas tau pom tias tau tshwm sim los ntawm thawj Y chromosome. Lwm cov noob ntawm tib neeg Y chromosome tshwm sim los ntawm autosome uas fused nrog tus thawj Y chromosome.
Cov noob dab tsi pom tsuas yog ntawm X chromosome?
Cov kws tshawb fawb tsis tau txiav txim siab seb cov noob twg ntawm X chromosome yog lub luag haujlwm rau feem ntau ntawm cov yam ntxwv ntawm Turner syndrome. Txawm li cas los xij, lawv tau txheeb xyuas ib lub noob hu ua SHOXuas yog ib qho tseem ceeb rau kev txhim kho pob txha thiab kev loj hlob. SHOX noob nyob hauv thaj tsam pseudoautosomal ntawm cov chromosomes kev sib deev.
Chromosome twg muaj SRY noob?
Tus SRY noob muaj nyob ntawm tus Y chromosome. Lub cheeb tsam kev sib deev txiav txim siab Y protein uas tsim los ntawm cov noob no ua raws li qhov hloov pauv, uas txhais tau hais tias nws txuas (khi) rau cov cheeb tsam tshwj xeeb ntawm DNA thiab pab tswj kev ua haujlwm ntawm cov noob tshwj xeeb.

Qhov kev hloov pauv twg muaj ob lub chromosome?
Yog hais tias kev sib koom ua ke ntawm cov chromosome uas tawg lawm xaus nrog ob chromosomes, ob qho kev txawv txav chromosomes tshwm sim: txhua tus muaj ib feem tau los ntawm lwm cov chromosome thiab tsis muaj ib feem ntawm nws tus kheej. Cov no yog hu ua translocations .
Can gene kelly hais lus Fabkis?
Tshaj tawm ntawm nws txoj haujlwm txawv tshaj plaw, Kelly qhia txog lub neej kev txawj ntse ntawm nws tus txiv - nws hais Fabkis zoo, "txoj kev Italian" thiab Yiddish . Gene Kelly kawm Fabkis li cas? Thiab thaum nws pib paub txog nws txoj hmoo ua ib tug neeg seev cev, nws kawm lus Fab Kis ntawmcov ntsiab lus ntawd, nyeem lawv cov lus qub kom txaus siab rau qhov tau hais.
Dab tsi yog bivalent chromosome?
Ib tug bivalent yog ib khub ntawm chromosomes hauv tetrad. Lub tetrad yog lub koom haum ntawm ib khub ntawm homologous chromosomes lub cev tuav ua ke los ntawm tsawg kawg ib qho DNA crossover. Qhov kev sib txuas ntawm lub cev no tso cai rau kev sib haum xeeb thiab kev sib cais ntawm homologous chromosomes hauv thawj qhov kev faib meiotic.
Dab tsi yog tus lej chromosome?
Gametes muaj ib nrab ntawm cov chromosomes uas muaj nyob rau hauv ib txwm diploid hlwb ntawm lub cev, uas tseem hu ua somatic hlwb. Haploid gametes yog tsim thaum lub sij hawm meiosis, uas yog ib hom cell faib uas txo cov chromosomes nyob rau hauv niam txiv diploid cell los ntawm ib nrab .
Dab tsi yog qhov txawv ntawm chromatin chromatid thiab chromosome?
Dab tsi yog qhov txawv ntawm chromatin, chromatids, thiab chromosomes? Chromatin yog DNA thiab cov proteins uas tsim los ntawm chromosome. Chromosomes yog cov khoom sib cais ntawm DNA hauv ib lub cell. Thiab Chromatids yog zoo tib yamdaim DNA tuav ua ke los ntawm ib lub centromere .
