A similarity and difference between prokaryotic and eukaryotic gene organisation

A similarity and difference between prokaryotic and eukaryotic gene organisation

by Visalakshi Venkatachalam -

Similarity : the DNA is supercoiled in both eukaryotic and prokaryotic gene organisation. 

Difference: 

1) Nucleosome(146bp + histone octamer) is PRESENT in eukaryotes.

Nucleosome is ABSENT in prokaryotes. 

2) Chromatid structures are present in eukaryotes. 

Chromatid structures are absent in prokaryotes. 

3) DNA is present in defined nucleus in eukaryotes. 

DNA is not well defined,  the place where it is found is called nuclein.

IM ADDING AN EXTRA POINT HERE FOR SIMILARITIES AND DIFFERENCE
SIMILARITIES
both prokaryotes and eukaryotes present with coding region to synthesize protein and functional RNA molecules
DIFFERENCE
the presence of introns in eukaryotic genes. Prokaryotic genes lack introns
