The concept of diagnostic reference levels (DRLs) is recognised as an efficient and powerful tool in optimization of diagnostic X-ray examinations.

Increased size of eukaryotic genomes necessitated the use of multiple origins of DNA replication, and presumably selected for their efficient spacing to ensure rapid DNA replication. The sequence of these origins remains undetermined in metazoan genomes, leaving important questions about the selective constraints acting on replication origins unanswered. We have chosen to study the evolution of...
