Explaining the DNA structure, 3D animation with basic narration

The Double Helix
Considering the complex functions of DNA, its structure is simple. The two DNA strands run in opposite directions and twist together to form a stable double helix. During replication or gene transcription, the 2 strands unwind and unzip. This allows one or both strands to be copied after which the strands are able to re-associate and twist back to their helical structure.
