Compositional differences within and between eukaryotic genomes

摘要

Interpretations on the mechanisms maintaining these profile differences center on genome-wide replication, repair, DNA structures, and con- text-dependent mutational biases. It is also observed that mitochondrial genome signature differences between species parallel the corresponding nuclear genome signature differ- ences despite large differences between corresponding mito- chondrial and nuclear signatures. The genome signature differences also have implications for contrasts between ro- dents and other mammals, and between monocot and dicot plants, as well as providing evidence for similarities among fungi and the diversity of protists.
