Image shows a z-series of a mouse ES cell carrying a multi-copy alpha-globin BAC transgene array. Relative distribution of the BAC sequences, identified by DNA FISH (green) using the entire BAC as pr...

A time lapse experiment of Saccharomyces cerevisiae expressing GFP-tagged MCM1. MCM1 is a transcription factor involved in cell-type-specific transcription and pheromone response; plays a central r...

Mouse myoblast cells were engineered to express GFP-PCNA (proliferating cell nuclear antigen) as a marker for replication factories, and also immunostained for DNA ligase. DNA was localized using Hoec...

Images of negatively stained chromatin fibers prepared from tandem arrays of a nucleosome positioning sequence reconstituted with purified histones. These samples contained 80 repeats of a 167 bp DNA ...

Transmission electron micrograph of a thin section of the nucleus of a HeLa cell expressing a mutant of the nuclear porin ALADIN. The nuclear envelope ultrastructure is not affected by the mutation. ...

Transmission electron micrograph of the salivary gland of the tick Rhipicelphals appendiculatus illustrating the dramatic difference in nuclear size seen in different cell types. Here, the large (prob...
