This is a Powerpoint presentation on DNA, RNA and Genetic Mutations. This can be for a high school Biology class. The presentation also includes the concepts of Replication, Transcription and Translation. Types of genetic mutations, and how is leads to changes in the production of proteins is also in this presentation. The slides have animation to introduce each new note on the page. There are few illustrations, but I have included links to illustrations that I use as well as two video to show the process of Transcription and Translation. There is also a link to an interactive activity from PBS. I use the activity to review the concept of Replication, Transcription, and Protein Synthesis. Some of the links to the videos do not load the first time. I have to reload them a couple of times for them to load properly or highlight the window and press enter. I use the Biology Coloring Workbook to show the DNA double helix, and Replication. I also perform a activity where students make there DNA model from candy. This is a separate product found in my store. This lesson can be modified for Jr. High School students. The time frame is dependent on how many labs/activities are done during the lesson.
