A nice tutorial on DNA structure. The menu at the bottom allows you to view some different information.

A collection of video lectures from a chemical structure and reactivity course taught at the University of California, Berkeley. The course teaches conjunction, aromatic theory, carbonyl compounds, carbohydrates, amines, carboxylic acid....

View a colorful 3-D diagrams of viruses and learn about how their structure helps them infect plants, animals, and bacteria.

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.

This resource provides a detailed diagram of animal, bacterial and plant cells and viral structure. Also included are detailed drawings, with definitions, of each of the cellular organelles.

Take an interactive quiz over the molecules of life. After completing the quiz, check your score, and then revisit any incorrect question for further review.

A collection of video lectures from a professor at the University of California, Berkeley for a chemical structure and reactivity course. The course teaches about aromatic compounds, electronic spectroscopy, and the reactivity and...

Here you can learn about biochemistry, the chemistry of the living world. Content explores carbohydrates, lipids, amino acid structure and proteins, enzymes, nucleic acids, and metabolism.

A brief text overview of DNA structure and an introduction or mention of the various forms of DNA.

Online biology textbook discussing the chemical nature of water, and the importance of its molecular structure to life. Also discusses at length the organic molecules nucleic acids, proteins, lipids, and carbohydrates.

Read about the co-recipient of the 1962 Nobel Prize in Medicine. This biography includes a picture of Crick as well as information on his personal life. Most focus, however, is on his scientific contributions and discoveries "concerning...

RNA, the genetic messenger, makes sure the DNA recipe gives your cells exactly what they ordered. But sometimes that means inhibiting some other RNA that got the recipe wrong. This process is called RNA interference (RNAi), and it acts...

Tutorial provides an overview of the structural features of carbohydrates, lipids, proteins, and 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
