In eukaryotes chromosomes are packaged into successively hig

In eukaryotes, chromosomes are packaged into successively higher-order structures, such as the 30 nm filaments. In bacteria, DNA is not packaged into such stable proteinaceous structures, and histonelike proteins bind to the DNA less tightly. Suggest an explanation for this difference.

Solution

Eukaryotic cells have larger genome compared to prokaryotes. The length of DNA in each one of human cells (eukaryotic) is roughly 2 meters!. To fit such a large genome into tiny nucleus the DNA is packaged into successively higher-order structures.

Bacterial DNA (prokaryote) is small in size and bacteria have shorter generation time which means the DNA needs to be synthesized more often. A relatively free genome of bacteria facilitates rapid DNA replication. Eukaryotic cells generally have longer generation time and complex cell cycle.
