Figure 6From: Activity map of the tammar X chromosome shows that marsupial X inactivation is incomplete and escape is stochasticExpression and localization of ATRX by RNA-DNA FISH in female fibroblast nuclei. (a,b) Sequential ATRX RNA (red) and DNA (green) FISH reveals that either one (a) or two (b) RNA-FISH signals co-localize with the DNA signals. Nuclei are counterstained with DAPI (blue).Back to article page
