7 Comparative Microbial Genomics group Center for Biological Sequence Analysis The Technical University of Denmark DTU What have we learned from 300 sequenced bacterial genomes? 1. Genetic diversity is greater than we thought. 4. Generally G’s are biased towards the leading strand, but the strand bias of A’s is tax-specific. 2. Very large genomes tend to be GC-rich, whilst small genomes tend to be AT-rich. 3. There are patterns, both locally and globally of AT-richness in bacterial chromosomes.
