Molecular Genetics Help

[The Rose Dragon]

I have a molecular genetics midterm this Tuesday, and I don't have a book. Are there any good online sources for operons, transcription and attenuation that explains in at least some detail those topics?

I don't know any off the top of my head so I asked google and checked a couple hits:

Link (http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookGENCTRL.html)-this one has some basics on operons, transcription and other gene expression, but no attenuation, one of the best ones I found digging around, has info on most basic concepts.
(I got redirected here from a MIT page that was no longer updated)

I felt that this one (http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/L/LacOperon.html#repressor) was fairly good about operons, but I neglected to check some of the other pages there.

As much as I dislike the wiki, it might actually be worth it depending on whether or not you can dig out some other, good, resources. wiki. (http://en.wikipedia.org/wiki/Attenuator_%28genetics%29)
