Question:
Why is coding DNA less coiled than non coding( transcriptionally inactive) DNA?



Replies:
Hi Mona,

Thanks for the question. I think that coding DNA is less coiled since it needs to be read during the transcription process. If the DNA is coiled, the transcription enzymes are unable to "read" the DNA.

I hope this helps. Please let me know if you have more questions. Thanks Jeff
