DNA Tube is a video site for scientific documentaries on unwinding the duplex DNA and understanding the science behind the subatomic world of matter. It's a weird niche I'll give them that, but the videos. Ads are also quite in your face on DNA Tube, and compounding the problem is that there are many videos which have nothing to do with DNA or science ("CSS - Media Property" video comes to mind).

The site offers a slow-down feature, which is pretty neat albeit useless for many of the videos housed on the site (not sure why you would need it). There's also little activity on the site in both comments and videos uploaded to the site.

DNA Tube falls short of its claims of providing educational science videos. The content, while educational in nature, appears to be all the over place and there really are too many ads on this site to be useful to children and educators alike. All in all, there are better sites for science and DNA content - including the Discovery Channel's video section and YouTube's science section.
