The history of our understanding of the DNA molecule is surveyed through the first half of this presentation. Once Watson and Crick are introduced, the focus shifts gears to the double-helix structure of the DNA molecule. That is all that you will find in this brief, but befitting set of slides. Use it as an introduction to the wonders of DNA in your biology class, then have learners build a model of the DNA molecule.
This sequence of slides covers each main macromolecule that is involved with human structure and function. The history of nucleotide research and the way that they are formed is summarized, a diagram accompanies the explanation. The main examples of their function are listed.
Sometimes a graphic organizer really helps learners grasp related concepts. On this short and simple worksheet, biology learners complete a concept map that encompasses the history of our understanding of DNA structure as well as the basics of the double helix molecule. Use this when you are teaching the topic, or hand it out as a quick review afterwards.
A lively presentation presents general facts and history of nucleic acids in a note-taking format. Every slide contains colorful photos or graphics to illuminate and engage. Biology aces learn about the function and structure of these essential molecules. After showing this presentation, have them create models of the double helix out of various craft materials.
Young scholars explore the structure of DNA and build a model. In this DNA lesson plan, students complete a chart with the molecules that make up both DNA and RNA nucleotides. Young scholars draw and color pieces of the molecule such as the hydrogen bonds and the bases. Students construct a model of DNA using plastic pieces to form a double helix and answer questions about the backbone and the bases of DNA.
