This animation explores the chemical components and bonds of the nucleotides that make up DNA.
As shown in the animation, DNA is a polymer of units called nucleotides, which contain deoxyribose sugars and nitrogenous bases. The nucleotides are linked in a directional manner via phosphodiester bonds between their sugars. The nitrogenous bases also form hydrogen bonds with one another based on predictable base pairing rules: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).
Depending on students’ background, it may be helpful to pause the animation at various points to discuss different parts of DNA’s structure.
Please note that embedded interactions will not appear in the descriptive audio version.
Video The Chemical Structure of DNA
This tool can be used to turn any BioInteractive video into an “interactive video” that includes pause points, questions, and labels. Educators can use the tool to create an interactive video, then share a link to that video with students. The tool also contains a library of interactive videos created by BioInteractive. Additional information can be found on this resource’s webpage.
You can access these features from the Interactive Video Builder landing page and top menu:
All interactive videos can be shared with students by copying links. At the end of each video, students will be prompted to review and submit their answers, which they can save as a PDF.
For more information on using these features, refer to the materials on this resource’s webpage.
This resource is optimized for use on desktops. It is supported by the most recent versions of Google Chrome, Firefox, Microsoft Edge, and Safari web browsers. On mobile devices, such as phones and tablets, playing interactive videos works well, but creating interactive videos may be suboptimal.
Most components of this resource have been designed, optimized, and/or tested for accessibility compliance (WCAG Level 2.0 AA Success Criteria). A few controls are not optimized for screen readers. For example, adding and editing interactions requires users to switch between “browse” and “forms” modes when inputting data. Navigation tips have been added where applicable.
