Genomic and RNA amplification. A. Schematic representation of a HeT-A element containing the 5'UTR (dotted box), the gag gene (black box) and the 3'UTR (lined box). Black bars at the bottom mark the amplified fragments. B. Genomic amplification of the indicated fragments in both, Oregon-R and GIII. Note the size variability of the amplified products indicative of size polymorphism among different HeT-A genomic copies. C. RNA amplification of the indicated fragment in both, Oregon-R and GIII stocks. +/- indicate specific amplification of sense and antisense strand respectively. GC indicates control for genomic DNA amplification.
