Figure 4. Electrophoresis gel showing the amplification of Exon 1 and Exon 2 of BRCA1 by PCR. The amplification of Exon 1 and Exon 2 verifies the integrity of mRNA transcription starting site that will permit translation further. The amplification of GAPDH gene was used as a control for DNA amplification accuracy and gel loading
