BBC Knowledge & Learning (K&L) is exploring a range of topics, from social history to science, in a series of three-minute online Explainer documentaries. In this case, London-based Territory Studio was commissioned to produce an animated film on the subject of DNA. The Territory team, led by art director/ animator William Samuel, chose a primer-like retro approach that didn’t veer off into futuristic complexities. The graphics are kept simple and elegant, using mostly circular shapes, a limited color palette and mostly circular movements to explain the double helix of DNA. The information also is succinct and accurate, with molecular biologist Dr. Matthew Adams teamed with writer Andrew S. Walsh to distill the text to the most fundamental elements required to understand how DNA functions and affects living beings.
