This resource is a PowerPoint presentation on DNA for high school biology. Topics covered include: Chargaff, base pairs, Franklin, Watson, Crick, nucleotides, purines, pyrimidines, replication, RNA, transcription, mRNA, tRNA, codon, anticodon, rRNA, and translation. Slide #45 has a particular nice animation of the translation process. This resource is part of the Developing Biology course which contains units on Microscopes; Biochemistry; Cells; Cellular Transport; DNA; Photosynthesis and Respiration; Mitosis and Meiosis; Genetics; and Evolution.
