Genome organisation in the murine sperm nucleus
Published online by Cambridge University Press: 26 September 2008
Summary
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.
