For GenoCon2 2012 Contest entrants special notices. http://GenoCon.org Design synthetic DNA sequences on the computer as solutions to complex problem assignments. Design a plant promoter DNA sequence using the PromoterCAD software to search for functional regulatory DNA. Make a promoter which controls specific expression in a plant tissue such as leaf, stem, or root, or only at a particular time of day. Accepted DNA designs will be synthesized, transformed into real plants, and tested for gene expression! Tools used on this platform allow you to create easy and accessible solutions to problems, even for non-specialists and students. Challenge yourself today!
