Figure 5. Schematic depiction of electron micrograph image of single-stranded EcoRI cleavage product A hybridized with hexon mRNA. Both DNA and RNA are shown in black. Does the micrograph in Figure 5 support or refute Sharp’s idea of introns? Explain. Label relevant areas of the micrograph from Figure 5 in your interpretation (introns, exons, RNA, single-stranded DNA, double-stranded DNA, and RNA-DNA duplexes).
