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.

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

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

The Inner Life of a Cell. Amazing "realistic" animations of many molecular structures and processes, with a fairly technical voiceover explanation. You will need a lot of cell biology to follow it -- I suggest you don't even try; just appreciate the general impression. It starts automatically after about five seconds of a static warning about educational uses. 8 minutes.

Incredible graphics and a clear but dry narration show the rotating molecular motor that makes ATP, the chemical fuel essential to all life. You can follow it with a basic intro or AP biology background. Remember that I said there are almost no wheels among living things? This is a crucial exception, at a molecular scale where rotary motion creates fewer problems.
