I added a new image of the lac operon repression mechanism but I could not locate the previous editor to inform them of my changes. Instead I'll post it here and hope they see it. ~YaguchiA
Hi YaguchiA. I'm not the one who created the original figure, but I reverted your image because the the promoter region of the lac operon does not contain UP elements. I recommend that you remove the UP elements and the blue "lollipops" representing the alpha subunit from your image and reinsert the figure. CatPath (talk) 16:57, 11 October 2012 (UTC)
