The video shows a 3D model of a DNA strand rotating in a dark background. The DNA strand is made up of a series of interconnected circles and lines that represent the base pairs and the sugar-phosphate backbone. The colors used in the video are mainly shades of yellow and orange, with the DNA strand itself glowing brightly against the dark background. The rotation of the DNA strand allows for a 360-degree view of the model, highlighting the intricate details and structure of the molecule.
