Teaching is NOT about repetition.  It involves exploring concepts, challenging explanations, and understanding examples.  Nothing helps to excite and reinforce an idea as much as full immersion.  So, for the Biology Teacher just beginning the new unit on DNA, Genetics, Chromosomes and all of the related proteins that make up life itself, may we recommend this shirt be worn sometime early in the first week during which you introduce this topic.  Featuring a standard model of the double helix along with a computerized version, sandwiching an actual x-ray diffraction photograph of a DNA molecule, this design has enough Adenine, Thymine, Cytosine and Guanine to add some extra life to any lesson, not to mention your wardrobe.  Now, when you're ready and need the perfect shirt for week 2, please see our ebay listing # 113886505609 to help demonstrate that there actually can be a fun side to life...and life science!  Perfect for the Molecular Biologist kicking back on the weekend but still allowing you to geek out as you chill out.
