CB association with U2 gene loci relative to RNA accumulation

	Gene only with CB (no RNA detected)	RNA with CB (RNA signal separate from gene)	Gene plus RNA with CB
Percent of U2 signals scored	43.3 (52/120)a	5.0 (2/40)	51.0 (125/245)

Three-color detection of U2 gene loci (DNA), RNA (using the 6.1-kb U2 locus probe), and CBs (Fig. 3) was used to determine if CB association was related to the presence of detectable RNA accumulations. The difference in CB association seen in genes with and without detectable RNA accumulations (51 vs. 43%) was not deemed to be significant. RNA signals separated from the genes did not appear to associate with CBs at significant levels.
