Figure 4From: Activity map of the tammar X chromosome shows that marsupial X inactivation is incomplete and escape is stochasticCoordinate transcriptional activity of neighboring X-borne loci assayed by two-color RNA-FISH in male and female fibroblasts. Loci are color coded above panels. (a) Male nuclei with transcription from two X-borne loci on the single X chromosome. (b) Female nuclei with transcription from two X-borne loci on the active, but not the inactive, X chromosome. Nuclei are counterstained with DAPI (blue).Back to article page
