“National DNA Day is a unique day when students, teachers and the public can learn more about genetics and genomics! The day commemorates the completion of the Human Genome Project in April 2003, and the discovery of DNA’s double helix.” – National Human Genome Research Institute

Nova PBS has a collection of interesting web exhibits surrounding DNA and other genetically coded materials:

Anatomy of Photo 51– Explore Rosalind Franklin’s famous x-ray image, a key to understanding the double-helix structure of DNA.

Before Watson & Crick – How did scientists discover that DNA was the blueprint of life?

Picturing the Molecules of Life – Over the past 50 years, scientific images of DNA, ribosomes, and RNA have catalyzed our understanding of biology.

If you have a favorite molecule, you can view it on your favorite Apple device with a free app called Molecules. The program allows you to display the structure in different rendering styles, rotate and zoom. You can even add custom molecular structures!
