Figure 3. Transcription start sites and 3′ end processing sites in the anti-sense region 1 of mod(mdg4). (A) 5′ and 3′ RACE reactions were used to map transcription start sites (TSS) and cleavage sites (CS) in total RNA purified from S2 cells. The figure compiles the TSSs and CSs identified by the RACE experiments. (B) The figure shows the nucleotide sequences of the TSSs and CSs. TSSs, polyadenylation signals and CSs are highlighted in orange.
