Spliced gene length as a function of normalized EST expression level Spliced gene length is plotted as a function of normalized expression level (arbitrary consistent units) for C. elegans. Expression level is estimated by abundance within the EST database [22] and normalized for the length bias of the abundance within the EST database method that is proportional to length, Eq. 1. The standard errors are indicated by the error bars.
