Congratulations!  You survived your first week of teaching DNA in your Biology class!  Maybe with a little help from our DNA-THE CODE OF LIFE shirt (Please see ebay listing # 173491823136), your students should now have a basic understanding of the concept and significance of the double helix and its base pairs of AT and CG.  Now, for week 2, it is time to dive into the real fun of chromosomes, genes, genomes, replication, heredity...and everything else that is the basis for life as we know it.  You can already hear the groans.  So, now is the perfect time to liven things up with the "lighter" side of life before your students have a chance to comprehend that this is just where it all starts.  NOW is the PERFECT time to show up wearing THIS SHIRT!  See?  BIOLOGY CAN BE FUN!  (Well, so I've been told.  I think Biology is yucky.  As an Astronomer, I think Astrophysics is FUN...but that's a COMPLETELY different set of shirts!  Good luck with Bio...)

From our current selection of top selling T-shirts!  Up for sale is a fun t-shirt celebrating the building blocks of life itself, the DNA molecule.  This design has been consistently popular for well over 20 years now and until someone finds a way to have life WITHOUT DNA, this design should remain popular and relevant for the foreseeable future.  These are BRAND NEW, FIRST QUALITY, preshrunk 100% cotton shirts, available in size SMALL, MEDIUM, LARGE, XL, XXL (EXTRA EXTRA LARGE, DOUBLE XL, 2XL), and/or XXXL (TRIPLE XL, 3XL).  This is an original multi-color design, screen-printed onto top quality GILDAN ULTRA COTTON shirts for durability and long life...this is NOT some cheap iron-on design.  Suggested to sell for $25.00 ($27.00 for 2XL, $29.00 for 3XL) and up (plus shipping), I am offering these for $24.00 each ($26.00 for 2XL, $28.00 for 3XL), which includes free shipping to anywhere in the U.S.   You can combine this with other items that I am selling to receive a refund for each additional item after the first, once shipped.  This refund reflects my savings in postage fees by combining your orders and is based on the total weight of the items.  International buyers are eligible for the multi-item discount (WHEN YOU USE THE SHOPPING CART FEATURE AND PAY FOR ALL OF YOUR ITEMS IN A SINGLE PAYMENT!) and receive free shipping to the Global Shipping Program Center in Kentucky, USA, but are responsible for all additional fees for postage, customs, tariffs, and/or other import charges.  Any questions?  Contact me.
