Feem ntau ntawm cov khoom siv caj ces raug teeb tsa rau hauv chromosomes uas muaj cov DNA uas tswj cov haujlwm ntawm tes. Prokaryotes feem ntau yog haploid, feem ntau muaj ib lub voj voog chromosome pom hauv nucleoid. Eukaryotes yog diploid; DNA tau teeb tsa rau hauv ntau cov kab chromosomes pom nyob rau hauv nucleus.
Hauv qhov no, dab tsi yog cov khoom siv caj ces ntawm prokaryotes?
DNA
Ib yam li ntawd, dab tsi muaj tseeb txog cov khoom siv caj ces hauv cov hlwb prokaryotic thiab eukaryotic? Cov lus teb yog - Prokaryotic hlwb muaj ib tug DNA, thiab eukaryotic hlwb muaj ntau chromosomes. Qhov sib txawv tseem ceeb ntawm prokaryotic thiab eukaryotic hlwb yog tias eukaryotic hlwb muaj ntev tangled strands ntawm DNA ntim rau hauv lub nucleus, thiab prokaryotic tsis muaj nucleus thiab lawv cov DNA yog luv stranded.
Hauv qhov no, dab tsi yog cov khoom siv caj ces ntawm eukaryotes?
DNA
Dab tsi yog qhov zoo sib xws ntawm prokaryotes thiab eukaryotes?
Zoo li ib prokaryotic cell, ib eukaryotic tshuaj cell muaj plasma membrane, cytoplasm, thiab ribosomes, tab sis a eukaryotic tshuaj cell feem ntau loj dua ib prokaryotic cell, muaj ib tug tseeb nucleus (lub ntsiab lus nws DNA yog surrounded los ntawm ib daim nyias nyias), thiab muaj lwm yam membrane-bound organelles uas tso cai rau compartmentalization. ntawm muaj nuj nqi.

Dab tsi txuas cov kab mob hauv lub cev thaum sib pauv cov khoom siv caj ces?
Bacterial conjugation yog kev hloov cov khoom siv ntawm cov kab mob ntawm cov kab mob los ntawm kev sib cuag ntawm tes-rau-cell los yog los ntawm tus choj-zoo li kev sib txuas ntawm ob lub hlwb. Qhov no tshwm sim los ntawm apilus. Cov ntaub ntawv thegenetic hloov pauv feem ntau muaj txiaj ntsig zoo rau tus txais
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Dab tsi yog cov khoom siv caj ces hauv eukaryotes?
DNA Tom qab ntawd, qhov twg yog cov khoom siv caj ces hauv lub cell eukaryotic? Cov Nucleus thiab Ribosomes. Pom hauv eukaryotic hlwb , lub nucleus muaj cov cov khoom siv caj ces uas txiav txim siab tag nrho cov qauv thiab kev ua haujlwm ntawm qhov ntawd cell .
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
Dab tsi yog tus cab kuj ntawm cov khoom siv caj ces?
DNA yog replicated thiab xa mus rau lwm tiam neeg kom lub hlwb ua tau tib yam dej num raws li cov niam txiv ntawm tes. Yog li, DNA uas code rau noob yog suav hais tias yog tus nqa khoom ntawm cov ntaub ntawv caj ces hauv feem ntau ntawm cov kab mob nyob
