?Autosome. Ib qho autosome yog ib qho ntawm cov lej chromosomes, as opposed to the kev sib deev chromosomes . Tib neeg muaj 22 khub ntawm autosomes thiab ib khub ntawm kev sib deev chromosomes (X thiab Y). Autosomes tau suav nrog kwv yees li ntawm lawv qhov ntau thiab tsawg.
Ua li no, dab tsi chromosomes yog autosomes?
Nees nkaum ob ntawm cov khub no, hu ua autosomes, zoo ib yam ntawm cov txiv neej thiab poj niam. Lub 23rd khub, lub kev sib deev chromosomes , txawv ntawm txiv neej thiab poj niam. Cov poj niam muaj ob daim qauv ntawm X chromosome, thaum txiv neej muaj ib qho X thiab ib qho Y chromosome. 22 autosomes yog suav nrog qhov loj me.
Tom qab ntawd, lo lus nug yog, qhov txawv ntawm autosome thiab chromosome yog dab tsi? Qhov loj qhov sib txawv ntawm tus chromosome thiab autosome yog li, txhua autosome yog a chromosome , tag nrho chromosomes tsis yog autosomes . Autosomes muaj homologous khub, whereas ib co chromosomes muaj txawv khub: hauv a txiv neej, poj niam txiv neej yog txiav txim los ntawm XY.
Ib tug kuj yuav nug, autosomes yog dab tsi?
Ib autosome yog ib qho chromosome uas tsis yog poj niam txiv neej chromosome (ib qho allosome). Cov tswv cuab ntawm ib autosome khub nyob rau hauv ib tug diploid cell muaj tib morphology, tsis zoo li cov nyob rau hauv allosome khub uas tej zaum yuav muaj ntau yam qauv. Autosomes tseem muaj cov noob txiav txim siab kev sib deev txawm tias lawv tsis yog chromosomes kev sib deev.
Autosome code yog dab tsi?
Autosomes yog suav chromosomes uas muaj cov noob rau txhua yam uas ua tsis muaj feem cuam tshuam txog kev sib deev. Tib neeg muaj 22 khub ntawm autosomes (los yog 44 nyob rau hauv tag nrho) uas yog tus lej 1 txog 22. Cov lej no qhia qhov loj ntawm qhov autosome . Piv txwv li, chromosome 1 yog qhov ntev tshaj plaws, thiab chromosome 22 yog qhov luv tshaj.

Dab tsi yog qhov txawv ntawm chromosomes chromatids thiab homologous chromosomes?
Nws yog ib qho tseem ceeb kom nco ntsoov qhov sib txawv ntawm tus muam chromatids thiab homologous chromosomes. Sister chromatids yog siv nyob rau hauv cell division, zoo li nyob rau hauv lub cell hloov, whereas homologous chromosomes yog siv nyob rau hauv reproductive faib, zoo li ua ib tug neeg tshiab. Sister chromatids yog genetic tib yam
Dab tsi ntawm chromosomes ua cov spindle fibers txuas rau txhawm rau txav cov chromosomes ncig?
Nws thiaj li, cov microtubules txuas los ntawm centrioles ntawm cov ncej ntawm lub xov tooj ntawm tes txuas mus rau txhua lub centromere thiab txhim kho mus rau hauv spindle fibers. Los ntawm kev loj hlob ntawm ib kawg thiab shrinking rau lwm yam, spindle fibers dlhos cov chromosomes raws nruab nrab ntawm lub cell nucleus, kwv yees li equidistant los ntawm spindle ncej
Muaj pes tsawg chromosomes autosomes muaj?
22 autosomes
Dab tsi yog txhais los ntawm tus lej diploid ntawm chromosomes?
Cov ntsiab lus kho mob rau diploid Muaj ob pawg ntawm chromosomes lossis ob npaug ntawm tus lej haploid ntawm chromosomes hauv cov kab mob ntawm tes, nrog rau ib tus tswv cuab ntawm txhua tus chromosome khub tau los ntawm ovum thiab ib qho los ntawm cov phev. Tus lej diploid, 46 hauv tib neeg, yog cov chromosome ib txwm ua tiav ntawm cov kab mob hauv lub cev somatic
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
