Hauv prokaryotes, lub voj voog chromosome yog muaj nyob rau hauv lub cytoplasm nyob rau hauv ib cheeb tsam hu ua lub nucleoid. Nyob rau hauv sib piv, nyob rau hauv eukaryotes, tag nrho cov cell chromosomes yog khaws cia rau hauv ib tug qauv hu ua lub nucleus. Txhua eukaryotic chromosome yog tsim los ntawm DNA coiled thiab condensed nyob ib ncig ntawm nuclear proteins hu ua histones.
Yog li ntawd, dab tsi yog cov khoom ntawm eukaryotic chromosomes?
Eukaryotic chromosomes muaj xws li a DNA - protein ntau complex uas yog npaj nyob rau hauv ib tug compact yam uas tso cai rau lub loj npaum li cas ntawm DNA muab khaws cia rau hauv lub nucleus ntawm lub cell. Lub subunit npe ntawm chromosome yog chromatin. Lub hauv paus ntawm chromatin yog nucleosome.
Ib yam li ntawd, cov chromosomes nyob qhov twg hauv lub cell eukaryotic? Ntawm eukaryotes , cov chromosomes yog muaj hauv daim nyias nyias cell nucleus. Cov chromosomes ntawm a eukaryotic cell muaj feem ntau ntawm DNA txuas rau lub hauv paus protein.
Hauv qhov no, muaj pes tsawg chromosomes nyob hauv eukaryotes?
46 chromosome ua
Puas yog eukaryotic hlwb muaj chromosomes?
Tag nrho DNA hauv a cell tuaj yeem pom nyob rau hauv tus kheej daim ntawv hu ua chromosomes . Eukaryotic hlwb muaj ntau chromosomes uas undergo meiosis thiab mitosis thaum lub sij hawm cell faib, thaum feem ntau prokaryotic hlwb muaj tsuas yog ib ncig chromosome.

Dab tsi yog pom hauv eukaryotic hlwb tab sis tsis yog cov hlwb prokaryotic?
Eukaryotic hlwb muaj cov kab mob sib txuas ua ke, xws li cov nucleus, thaum cov hlwb prokaryotic tsis ua. Qhov sib txawv hauv cellular qauv ntawm prokaryotes thiab eukaryotes muaj xws li muaj mitochondria thiab chloroplasts, phab ntsa cell, thiab cov qauv ntawm chromosomal DNA
Dab tsi yog qhov txawv ntawm lub teeb pom kev thiab pom tsis pom?
Tsis muaj qhov sib txawv ntawm lub teeb pom kev thiab pom tsis pom lub teeb xws li xov tooj cua nthwv dej thiab X rays. Lawv yog tag nrho cov electromagnetic tsis txawv nyob rau hauv ib txoj kev xwb: lawv wavelength. Lub teeb ultraviolet, X rays, thiab gamma rays tag nrho muaj luv luv wavelengths tshaj li pom lub teeb
Kev pom kev pom hauv computer graphics yog dab tsi?
