Promoter Region

Postby star451 on Tue Apr 08, 2008 6:46 pm

Hey, anyone mind helping in this question.

Promoter regions are usually high in adenine and thymine. Explain how this helps intiate transcription.

Thymine and adenine form two hydrogen bonds when paired, while guanine and cytosine form three hydrogen bonds per bp. An AT-rich region is thus easier to melt because fewer bonds per bp hold it together.
