<div>Does anyone know where to find the statistics in general for a prokaryotic genome. I am looking for the parameters such as rate of substitution, transition transversion rate ratio and GC content for the photosynthetic prokaryotic genomes. I found the GC content, but somehow I could't locate the other two parameters. If anybody know the database or publications that has the information about the parameters (the one that I mentioned above) of a prokaryotic genome in general, please let me know. I would really appreciate it.
