DNA Structure (Core and AHL)
This is a short one – class presentation is here (click shadowed images for animations and movies):
Here’s a decent video from BBC AS Guru with David Suzuki:

And here’s a very stylized video of DNA structure from Hybrid Medical Animation. See if you can narrate it:

The story of the discovery of the double-helix structure is a good example international collaboration and competition, and led to the Nobel prize for Crick, Watson and Wilson (who we never hear about). You’ve got to feel for Rosalind Franklin – her work was key in their discovery and she wasn’t cited for it until after her death.
Here’s a great video, though the presenter sound like he has a mouth full of marbles:
Secrets of the Sequence – The Discovery of DNA
This 9-minute clip is an ideal ‘watcher’ to go along with the reader in the Course Companion – it tells the story of the discovery of the DNA double helix structure by Watson and Crick and how their discovery was dependant on the prior work of Rosalind Franklin and the compeitive/cooperative nature of research:
This clip is taken from the vdeo lesson resource provided by Virginia Commonwealth University’s ‘Secrets of the Sequence’ website. They have 50 different videos, each with accompanying lesson plans and activities.
They also have a YouTube channel: VCULifeSciences.
