Ethidium is a dye that's used in molecular biology to allow DNA to be visualized. Regular DNA isn't colored; it absorbs ultraviolet but not visible light, so you need to use tricks like making the DNA radioactive (which makes it pretty easy to spot), or using dyes that selectively bind to DNA.
Note that the animator (and researcher - he used real data) was a staff member of mine, named Drew Berry. Note also the animation won a BAFTA award in 2004. More stuff is available here, free for use by educators.
thanks for mentioning that site.
