Lub nucleus ntawm eukaryotic hlwb yog tsim los ntawm cov protein thiab deoxyribonucleic acid, lossis DNA. Lub DNA yog nruj nreem qhwv ib ncig ntawm cov protein tshwj xeeb hu ua histones; qhov sib xyaw ntawm DNA thiab histone proteins hu ua chromatin . Txawm tias prokaryotic hlwb tsis muaj nucleus, lawv muaj DNA.

Ib yam li ntawd, tib neeg nug, puas muaj chromatin nyob rau hauv prokaryotic lossis eukaryotic hlwb?

Chromosomes thiab Chromatin . Tsis tsuas yog cov genomes ntawm feem ntau eukaryotes complex ntau dua li cov prokaryotes tab sis DNA ntawm eukaryotic hlwb kuj raug teeb tsa txawv ntawm qhov prokaryotic hlwb . Cov genomes ntawm prokaryotes yog muaj nyob rau hauv ib chromosomes, uas feem ntau yog ncig DNA molecules.

Ib yam li ntawd, dab tsi muaj nyob hauv cov hlwb prokaryotic tab sis tsis yog eukaryotic? Prokaryotic Cell . Eukaryotic hlwb muaj cov membrane-bound organelles, xws li cov nucleus, thaum prokaryotic hlwb ua tsis yog . Qhov txawv hauv cellular qauv ntawm prokaryotes thiab eukaryotes suav nrog muaj mitochondria thiab chloroplasts, cov cell phab ntsa, thiab tus qauv ntawm chromosomal DNA.

Ib yam li ntawd, cov cell yog chromatin hauv dab tsi?

Chromatin yog ib pawg ntawm cov khoom siv caj ces muaj xws li DNA thiab cov proteins uas sib xyaw ua ke chromosomes Thaum lub sij hawm eukaryotic cell faib. Chromatin nyob rau hauv lub nucleus ntawm peb lub hlwb.

Cov qauv dab tsi tsuas pom muaj nyob hauv cov hlwb prokaryotic?

Cov ntsiab lus

  • Tag nrho cov cell muaj plasma membrane, ribosomes, cytoplasm, thiab DNA.
  • Cov hlwb prokaryotic tsis muaj cov nucleus thiab cov txheej txheem sib khi.
  • Eukaryotic hlwb muaj cov nucleus thiab cov txheej txheem ua ke hu ua organelles.
