This is a basic animation of how DNA is structured.

DNA is the molecule of life, as life's secrets are encoded in DNA. In this interactive activity. we see the famous double helix structure of DNA.

DNA Helix, DNA structure, DNA bases, Nucleotides, strands of DNA, Bonding in DNA, and bonding between bases are the topics delved into in this thorough site.

This site has a catalog of all known viruses, including a picture of each, structure, family, hosts, and more.

Explains how DNA contains genetic material and how it is housed in chromosomes. This lesson is 2 of 5 in the series titled "DNA."

This is a well structured presentation with lots of graphics on how proteins are formed from DNA and RNA.

Article about a recent book on Rosalind Franklin and the contribution she made to the discovery and identification of "The substance of life -- the structure of DNA."

This site from the University of Massachusetts links to downloadable freeware (Rasmol and CHIME) which are required to view 3-D images common on organic chemistry tutorials.

This lesson will introduce nucleic acids, including the two different types, their functions, and where they are found. It is 7 of 9 in the series titled "Nucleic Acids."

The 3-D model of Cytosine (C), Uracil (U), Adenine (A), and Guanine (G), the four nucleotide bases in RNA. Requires the CHIME plug-in to view the models, or they can be viewed statically in .gif format

This lesson will show the difference in structure between deoxyribonucleic acid and ribonucleic acid. It is 3 of 4 in the series titled "DNA vs RNA."

This lesson will show the difference in structure between deoxyribonucleic acid and ribonucleic acid. It is 4 of 4 in the series titled "DNA vs RNA."

This lesson presents how the structure and function of nucleic acids pertain to living things. It is 1 of 2 in the series titled "Structure and Function of Macromolecules: Nucleic Acids."

A good site that begins with the background and branches into the structure, function and applications of technology. This version of the page requires Java, and should open some applets that allow you to see the structures in 3-D.

A 3D computer generated model of humans DNA structure. The double helix image labels base pairs, diameter, major and minor grooves.
