Figure 1From: Normalization and experimental design for ChIP-chip dataExamples of binding sites for the Drosophila MSL complex on the X chromosome. (a) An example of typical binding regions. (b) An example of a very large binding region (about 18 kb). Corresponding mock controls show no binding. Genes transcribed from left to right are shown on top; red genes are expressed while black ones are not.Back to article page
