Then, a group of histones comes together to form a nucleosome. Finally, the string of nucleosome beads is coiled to condense the DNA even further.
DNA also contains all the genetic coding which is used to control functions, behavior and development of an organism. DNA is also used as a long term storage device to store the genetic instructions.
