Alternative splicing events. The bold line with squares with ORF/gene names shown at the top of each image indicates the genome map, and the arrows shown below the map indicate the transcripts. (A) YNL194C and YNL195C share the same promoter to generate three mRNAs (Left), including a potential bicistronic one detected as a ≈2,000-nt band in Northern blot analysis of SK1 cells (Right). IVT, in vitro transcription. (B) YMR148W has two distinct promoters, and YMR147W may be an upstream exon of YMR148W used in the transcript starting from the distal promoter. (C) A case of transcription-induced chimera between NCE101 and YJL206C.
