Subcellular RNA fractions have a different transcript composition. (A) Scatter plot and correlation matrix of all sequenced samples. The color intensity of the correlation boxes (r values) depicts the relative strength of the correlation, ranging between 0.39 and 0.97. (B) RNA species content of each sequenced fraction in counts per million. CPM, counts per million; lincRNA, long intergenic noncoding RNA; snoRNA, small nucleolar RNA; snRNA, small nuclear RNA.
