a single sheet of very small font DNA; size generates interest;
multiple uses: rows meant to simulate one continuous single-stranded segment of DNA; gives students an idea of just how many base pairs long a small piece of DNA is; helps students get a mental frame for understanding all processes that involve DNA both natural and manmade; used as introduction to molecular genetics or genetic manipulation techniques like gel electrophoresis. Have students search for and highlight all of the following hypothetical "recognition sequences" CATACTTAG as if the pen is a "restriction enzyme"; explain how a certain cut would be made by the r.e. at each instance of that sequence to create DNA fragments with "sticky ends"; I have paper labs for DNA fingerprinting and Gene Transfer and Cloning based on this introductory sheet; replication, transcription, and translation paper labs also available soon; p.2 is key ;there are 11
