Figure 2

The probability distributions of destabilization (SIDD) properties are shown for 100 bp long promoter, coding, and CON regions. We also partition the promoters from all known TSSs into those that are intergenic and those that overlap coding regions. (A) The SIDD parameter here is the sum over all 100 positions of the destabilization energy G(x); (B) The parameter used here is the minimum value G _m of G(x). Because the numbers of intergenic and coding promoters are different, these curves are plotted as probability density functions. In consequence, the area under each curve sums to 1, a choice which facilitates comparisons between different sized sets.
