Cover. Pseudo-coloured scanning electron micrographs of a ciliated protozoan, Oxytricha sp. This organism has two types of nuclei, a germinal micronucleus and a somatic macronucleus; the latter is a bag of individual genes, which is an unusual genome organization in eukaryotes. The image shows two protozoa, the larger presumably eating the smaller one; cannibalism is not unusual in this species. Gopal Murti is the Director of Scientific Imaging at St Jude Children's Research Hospital, Memphis, TN, and an adjunct professor of pathology at the University of Tennessee, with research interests in virus--cell interactions and leukaemic cell--stromal cell interactions. He believes that this protozoan, upon which he collaborates with Dr David Prescott, provides an ideal model to study eukaryotic chromosome structure and function.
