In the Noll experiment, the chromosomal material was digested with DnaseI, extracted with phenol, and then the DNA was run on a gel. The DNA bands were observed to be in multiples of 200 bp. Draw the nucleosome structure of a 600 bp fragment. A histone octamer can be drawn as a big circle.

Chromosomal and plasmid DNA can be cut into manageable pieces by
restriction enzymes. Using agarose gel electrophoresis, the DNA
fragments can be separated on a gel, based on their lengths. In
order to see the fragments, a stain is typically added to the gel.
The size of each fragment can be determined by comparing each one
to a DNA molecular weight marker of known size.
Below is a map of pBR22 plasmid. The position and base pair
number of the...
