Abstract Recently the mismatch between our newly acquired capacity to synthetize DNA at genome scale, and our low capacity to design ab initio a functional genome has become conspicuous. This essay gathers a variety of constraints that globally shape natural genomes, with a focus on eubacteria. These constraints originate from chromosome replication (leading/lagging strand asymmetry; gene dosage gradient from origin to terminus; collisions with the transcription complexes), from biased codon usage, from noise control in gene expression, and from genome layout for co-functional genes. On the basis of this analysis, lessons are drawn for full genome design. Copyright © 2012 Federation of European Biochemical Societies. Published by Elsevier B.V. All rights reserved.
