DNA PACKAGING
What Is DNA Packaging?
DNA Packaging is the folding of an organism’s DNA into a
compact structure that can fit within the nucleus of the cell.
How Is A DNA Packaged In A Cell?
DNA packaging in prokaryotic cells are much simpler
than eukaryotes. Let’s look at the DNA packaging in
eukaryotes.
DNA packaging starts with Naked DNA.
Histones are the main protein that responsible for DNA
packaging. The DNA wraps around histones. Histones
are positively charged proteins. So they can easily binds
with negatively charged DNA.
, There are few steps of DNA packaging.
1 .First Level Of DNA Packaging.
8 Separate histone molecules attaches to the DNA molecule
and forms a tightly packed structure called Nucleosome.
Nucleosome fiber is a basic structure of chromatin.
