Protein structure (primary, secondary, tertiary, quaternary). 51 seconds.

DNA structure video, a bit schematic. 1 minute 19 seconds.

How DNA is packaged into chromosomes, and how DNA replicates, with voiceover. Excellent. 3 minutes 6 seconds.

Relatively realistic visualization of DNA transcription (making mRNA from DNA). Music, no explanation. 59 seconds.

Protein synthesis cartoon lecture. Very dry, but clearly explained. 4 minutes 3 seconds.

Protein synthesis simulation. More realistic graphics, but not as clearly explained. 2 minutes 1 second.

The whole process of transcription to mRNA, followed by protein synthesis. Good semi-cartoon graphics, with narration. 2 minutes 50 seconds.

Music video: The Inner Life of a Cell. Incredible, accurate (but still simplified) visualization of many specific molecular "machine" processes in a human cell; mostly functioning of the cell, not genetics in particular. Beautiful. Music sound track. 2 minutes 50 seconds.

Narrated video: The Inner Life of a Cell. Longer version of above, with voiceover explanation. You will need a lot of cell biology to follow it. You first see just a static warning about education use. Just wait; the video starts automatically in about five seconds. 8 minutes.

Click here for more from Harvard multimedia! Check out the clip on the the lower left about ATPase, in which the chemical fuel of the cell (ATP) is produced by a rotating molecular motor. The concepts as well as the graphics are incredible, and you can follow it with a basic intro biology background.
