If a 1000 kb fragment of DNA has 10 evenly spaced and symmetric replication origins and DNA polymerase moves at 1 kb per
This outcome reflects nucleic acid structure and recombination, where hairpin formation, Holliday junction resolution and translation control ensure fidelity. Option C captures this correctly because it matches molecular mechanisms of gene expression, consistent with textbook descriptions and experimental observations in molecular biology.
Ref: Watson et al., Molecular Biology of the Gene, 7th Edition, Chapter 9, Transcription and RNA Processing, describes RNA hairpin formation, secondary structures and regulatory mechanisms controlling gene expression in prokaryotes and eukaryotes.
