Patterned transcription. Hybridization of cDNA probes to whole-mount embryos in situ reveals patterned expression in staged embryos. (A) cyclin B; (B) neuralized; (C) odd-skipped; (D–I) novel transcripts. Lateral views of embryos are shown inA–F, with dorsal up and anterior to the left. InG–I; ventral views are shown, with anterior to the left.
