DNA Extraction

Why didn''t all that grinding and chopping destroy the DNA? The DNA is so small and is coiled up so tightly by the histone proteins that it escapes most of the physical treatment. Once it is released from the histones by the enzyme solution, it unwinds into long strands and becomes much more fragile.
