This PowerPoint is a wonderful tool, to teach a sometimes tricky concept. This 85 slide PowerPoint presentation includes information regarding the structure of DNA. This PowerPoint includes easy-to-follow, but detailed descriptions of DNA structure, RNA structure, the role of DNA in protein synthesis, transcription, translation and codons. This PowerPoint also includes many diagrams and pictures to help ensure student understanding. I have used this PowerPoint with my grade 11/12 Biology class. This is a lengthy PowerPoint, with awesome information. I usually deliver this PowerPoint in at least three lessons. Feel free to download and edit this PowerPoint. Please do whatever works best for you!
