Eukaryotic genomes yog tsim los ntawm ib los yog ntau tshaj linear DNA chromosomes. Zoo li cov kab mob uas lawv pib los ntawm, mitochondria thiab chloroplasts muaj cov chromosome ncig. Tsis zoo li prokaryotes, eukaryotes muaj exon-intron lub koom haum ntawm cov protein coding noob thiab qhov sib txawv ntawm DNA rov ua dua.

Cov lus nug tseem yog, dab tsi yog nyob rau hauv genome?

A genome yog ib qho kab mob tag nrho ntawm DNA, suav nrog tag nrho nws cov noob. Txhua genome muaj tag nrho cov ntaub ntawv xav tau los tsim thiab tswj lub cev. Nyob rau hauv tib neeg, ib daim qauv ntawm tag nrho genome -ntau tshaj 3 billion DNA puag khub-yog muaj nyob rau hauv tag nrho cov hlwb uas muaj ib tug nucleus.

Kuj Paub, prokaryotic thiab eukaryotic genomes txawv li cas? Prokaryotes feem ntau haploid, feem ntau muaj ib lub voj voog chromosome pom nyob rau hauv nucleoid. Eukaryotes yog diploid; DNA tau teeb tsa rau hauv ntau cov kab chromosomes pom hauv cov nucleus. Prokaryotic thiab eukaryotic genomes ob leeg muaj noncoding DNA, kev ua haujlwm uas tsis nkag siab zoo.

Ib yam li ntawd, eukaryotic genome zoo li cas?

A genome yog ib qho kab mob tag nrho ntawm DNA, suav nrog nuclear thiab mitochondrial DNA. Eukaryotic genome yog linear thiab ua raws li Watson-Crick Ob Chav Helix qauv qauv. Embedded hauv Nucleosome-complex DNA & Protein (Histone) qauv uas ntim ua ke los tsim cov chromosomes.

Prokaryotic genome yog dab tsi?

Cov genome ntawm prokaryotic Cov kab mob feem ntau yog ib puag ncig, muab ob npaug rau ntawm DNA, ntau cov ntawv luam uas muaj nyob rau txhua lub sijhawm. Lub genophore yog DNA ntawm a prokaryotes . Nws yog feem ntau hu ua a prokaryotic chromosome.
