How do regulatory proteins identify specific nucleotide sequences without unwinding the DNA?
Describe the mechanism by which the transcription of $l a c$ genes is regulated in $E$, coli when glucose is absent but lactose is present in the environment.
What role does the methylation of DNA likely play in transcriptional control?
How does the primary RNA transcript of a cukaryotic gene differ from the mRNA transcript of that gene as it is translated in the cytoplasm?
How can a eukaryotic cell control the translation of $\mathrm{mRNA}$ transcripts after they have been transported from the nucleus to the cytoplasm?
