H3 acetylation is more pronounced in rapidly-dividing than stationary phase cells. The upper two tracks represent the ratio of acetylated histone H3 to total H3 signal from confluent stationary (day 9) cells and rapidly-dividing (day 3) cells, respectively. The vertical scale used normalizes the peak heights to those observed in stationary cells. The bottom track shows the position and strand of genes from chr36, which is 2682 kb in length.
