DNA Structure and Function Assessment

The video tutorial guides viewers through creating a double helix DNA model using beads and pipe cleaners. It begins by introducing the materials needed, such as beads in six colors, pipe cleaners, rulers, and scissors. The tutorial then explains how to construct the DNA model, including cutting pipe cleaners, beading strands, and creating rungs. It also provides a brief overview of DNA's structure and function, including base pairing and nucleotides. The video concludes with a recap of the materials and a completed DNA model.
