Figure 6-5DNA unwinding and rewinding by RNA polymerase
A moving RNA polymerase molecule is continuously unwinding the DNA helix ahead of the polymerization site while rewinding the two DNA strands behind this site to displace the newly formed RNA chain. A short region of DNA/RNA helix is therefore formed only transiently, and the final RNA product is released as a single-stranded copy of one of the two DNA strands.
