3. Eukaryotic cells package their DNA by wrapping short stretches of it around the rims of disk- shaped proteins called histones. Typically, a 150 base-pair segment of DNA (0.34 nm/base-pair) wraps itself 1.7 times around the histone core. DNA's persistence length is 53 nm and recall that persistence length is equal to the flexural rigidity (ke) divided by KbT.
