Gene expression patterns in the HeLa cells.

<p>a) The distribution of total transcripts shows that there are two populations, one low-abundance population and a second larger, high-abundance population. This dichotomy shows that the parameters used to search for low abundance transcripts was successful. b) A graphical representation of the cellular process that was distinguished based on Gene Ontology (GO), using the domain of cellular components in level 3; the amount of retrieved elements was compared against the total size of the pathway.
