The organisation of DNA sequences in the murine sperm nucleus was studied using in situ hybridisation of biotinylated DNA probes. The efficiency of this reaction was assessed using a dispersed repetitive DNA probe. Telomeric DNA was distributed around the nucleus. Centromeric and ribosomal DNA sequences occupied restricted domains in the sperm nucleus. DNA sequences for a transgene and a cluster of homeogenes occupied different, and rather less defined, domains. Together these results imply that both repetitive and protein-coding sequences are arranged in the nucleus in an ordered fashion.
