True activators of transcription are transcription factors that bind to
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, 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.
