||Primary source 26 abstract: "Nascent transcripts of the Drosophila Ubx gene were detected by in situ hybridization. Following onset of expression, the progress of RNA polymerase (1.4 kb/min) across the gene was visualized as the successive appearance of hybridization signals from different positions within the transcription unit. Nascent transcripts disappeared at mitosis."
||P.243 left column 3rd paragraph: "For comparison, in Drosophila, the larval Ultrabithorax genes are transcribed at ~1.4 kb/min (primary source 26) and stress-induced hsp70 genes at ~1.2 kb/min, in cells
growing in culture (primary source 27)."
