Abstract

Comparison of genome sequences from Eubacteria and Eukaryotic organelles shows that the order of genes in gene clusters encoding certain highly conserved cell division proteins and ribosomal proteins is itself highly conserved. Experiments with a cluster of cell division and related genes of E. colihave shown that this gene order is not essential for function. Comparisons between genomes also show that no pair of genes are necessarily adjacent in all genomes. The reason for the extreme conservation of order is therefore unknown, although one possible explanation might be the lateral exchange of tightly-linked groups of genes coding for co-adapted sets of proteins.
