Eukaryotic Chromosomes

The eukaryotic chromosomes are more complicated than procaryotic. They encode more information (coding and non-coding parts) so we recornize bigger count of chromosomes in Eukaryota. Their count depends on the evolution of the species. But they structure is pretty similar.

DNA contains milions and milions of nucleotides and it is neccesary to compress them. In eukyryotic chromosomes we recognize a process similar to supercoiling in Prokaryota. This is made possible by special proteins which packed the DNA strand. Complex of DNA and these proteins is called chromatin.
