The total length of DNA is so long that it cannot possibly fit inside a nucleus in its unfolded state. So DNA is folded and coiled around Histones for more compaction.
ANSWER: A copy of DNA is necessary in the process of protien synthesis.
They help fold and coil DNA to make it smaller.
DNA is necessary to construct proteins for the body.
RNA, which is produced by the nucleolus, is necessary for transporting the necessary information for DNA to clone itself.
