## Description

### Micrococcal nuclease control coverage, sense strand reads

The plot represents local coverage by control micrococcal nuclease fragments from cleavage of naked C. elegans DNA. By analogy with the experimental nucleosome data, 147 base pair sense segments starting from each of the individual control reads has been used to assemble a control coverage plot that accounts for enzymatic and sequencing biases of sampling from the reference genome.

### Micrococcal nuclease control coverage, antisense strand reads

The plot represents local coverage by control micrococcal nuclease fragments from cleavage of naked C. elegans DNA. By analogy with the experimental nucleosome data, 147 base pair antisense segments starting from each of the individual control reads has been used to assemble a control coverage plot that accounts for enzymatic and sequencing biases of sampling from the reference genome.
