WebbPCR allows conversion of any DNA fragment to a transcription template by appending the T7 (or SP6) promoter to the forward primer (Figure 2A). Additionally, poly(d)T-tailed reverse primers can be used in PCR to generate transcription templates with A-tails. This obviates the need for a separate polyadenylation step following transcription.
