Distribution of mean melting temperatures of all known exonic sequences in the human genome. Based on the melting profiles created by a PubGene-MIT-Beckman Coulter collaboration, the histogram comprises the melting temperatures of all 236,039 exonic sequences from a set of human 27,561 protein encoding genes derived by Ensembl, a joint project of EMBL-EBI and the Sanger Institute. The resolution is 0.1°C. Mean temperatures were calculated for each exon plus 50 intronic base pairs 3' and 5' to each exon to include mRNA splice sites. (Reproduced with permission of PubGene, Inc.).
