Feem ntau kab mob muaj ib los yog ob lub voj voog chromosomes.
Tom qab ntawd, ib tug kuj yuav nug, cov kab mob puas muaj chromosomes?
Thaum eukaryotes muaj ob lossis ntau dua chromosomes , prokaryotes xws li kab mob muaj ib leeg chromosome tsim los ntawm ob-stranded DNA nyob rau hauv ib lub voj. Cov DNA yog nyob rau hauv lub nucleoid ntawm lub cell thiab yog tsis cuam tshuam nrog protein ntau.
Ib yam li ntawd, chromosome ua dab tsi hauv cov kab mob ntawm tes? Koj DNA yog qhwv ib ncig ntawm cov protein los ua cov khoom hu ua chromatin, ntev daim uas yog hu ua chromosomes . Chromosomes yog cov qauv tsim los ntawm DNA thiab cov proteins. Hauv kab mob , cov chromosome tuav tag nrho cov ntaub ntawv tseem ceeb rau lub cell kom ciaj sia.
Kuj nug, cov kab mob puas tsuas muaj ib chromosome xwb?
Feem ntau cov kab mob muaj ib genome uas muaj ib ib DNA molecule (piv txwv li, ib chromosome ) uas yog ob peb lab lub hauv paus khub loj thiab yog "cim" (tsis yog muaj xaus zoo li chromosomes ntawm cov kab mob eukaryotic).
Muaj pes tsawg chromosomes nyob rau hauv tib neeg cell?
Hauv tib neeg , cwb cell ib txwm muaj 23 khub ntawm chromosomes , rau tag nrho ntawm 46. Nees nkaum-ob ntawm cov khub no, hu ua autosomes, zoo ib yam ntawm cov txiv neej thiab poj niam. 23rd khub, poj niam txiv neej chromosomes , txawv ntawm txiv neej thiab poj niam.

Yuav ua li cas cov cell nyob rau hauv ib tug multicellular kab mob ua tshwj xeeb?
Cellular sib txawv yog cov txheej txheem uas ib tug tsawg tshwj xeeb cell ua ib tug tshwj xeeb cell hom. Kev sib txawv tshwm sim ntau zaus thaum lub sij hawm kev loj hlob ntawm ib tug multicellular kab mob raws li lub cev hloov los ntawm ib tug yooj yim zygote mus rau ib tug complex system ntawm cov ntaub so ntswg thiab cell hom
Muaj pes tsawg qhov kev zam rau tus qauv electron configurations muaj nyob rau hauv D block?
ob Ntawm no, cov ntsiab lus twg yog kev zam rau Aufbau txoj cai? Piv txwv li, ruthenium, rhodium, nyiaj thiab platinum yog tag nrho kev zam rau Aufbau txoj cai vim yog sau los yog ib nrab puv subshells. Ib sab saum toj no, yog vim li cas electron configuration rau tooj liab 1s22s22p63s23p63d104s1 es tsis txhob 1s22s22p63s23p63d94s2?
Muaj pes tsawg txoj hauv kev genetic recombination muaj nyob rau hauv cov kab mob?
Muaj peb txoj hauv kev tseem ceeb uas genetic recombination tshwm sim hauv cov kab mob, thawj qhov hu ua transformation. Qhov no yog thaum ib daim DNA pub dawb los ntawm tus neeg tau txais kab mob
