Figure 1From: Systematic analysis of transcribed loci in ENCODE regions using RACE sequencing reveals extensive transcription in the human genomeFrequency of PCR products obtained from different genomic regions. Primers designed to the sense and antisense strands of exons, novel transcriptionally active regions (TARs) and nontranscribed regions were used to generate rapid amplification of cDNA ends (RACE) products. The frequency of PCR products obtained is indicated. nontx, region not previously shown to be transcribed.Back to article page
