  1. DNA The Blueprint of Life

  2. Basics of DNA • DNA stands for deoxyribonucleic acid. • James Watson and Francis Crick discovered the shape of DNA in 1953. DNA: Blueprint of Life

  3. Parts of a DNA Molecule • DNA contains four bases: • Adenine Thymine • Guanine Cytosine • Each base is part of a repeating link called a nucleotide. DNA: Blueprint of Life

  4. DNA Replication • DNA replication is the process of a DNA molecule making an exact copy of itself. • Steps of Replication • DNA unzips • Free-floating nucleotides attach • Bonds are reformed Animated DNA Replication DNA: Blueprint of Life

  7. PowerPoint Presentations PowerPoint presentations are a valuable tool for teachers to use to present information to students and parents. By using the various features of PowerPoint a teacher can make the information presented come to life and have more meaning to the audience. Students and parents will stay interested in the presentations longer than they would for a standard teacher lecture or meeting. By keeping their interest longer more of the information will be absorbed by them. In the PowerPoint presentation, DNA: The Blueprint of Life, I used several different features of the presentation software to enhance the information being presented. First, I used the same background and layout for each slide. I chose a blue background with yellow font and a picture of DNA along the left side of the slide for the design. DNA: Blueprint of Life

  8. According to A+ Rubric by Joan Vandervelde the layout of the slide needs to be “visually pleasing and contribute to the overall message” (“Vendervelde, Joan,” 2007). The blue background is visually pleasing and the incorporation of the DNA molecule picture on every slide allows the viewer to continually see what a DNA model looks like. Also, Dr. Lynell Burmark recommends the use of a blue background and yellow text in program four, “Multimedia Design, Part Two: Color and Music,” because blue is a cool color and recedes into the background and yellow is a warm color and will move to the foreground of the presentation (Laureate Education, Inc., 2002). Dr. Burmark also recommends highlighting or changing the color of any important information that needs to stand out from the rest of the text. She states that an item that is highlighted or in red is recognized 74% faster and recalled 80% of the time (Laureate Education, Inc., 2002). DNA: Blueprint of Life

  9. I incorporated this in my presentation on slides two, three, and four in order to emphasis the key vocabulary words and to correlate which bases of DNA pair together, The next feature that I used to enhance the presentation was sound. I inserted the classical tune from Microsoft’s sound gallery into the presentation so that it would calm the audience and create an atmosphere conducive to learning. I decided on this particular sound clip because it is played at around 60 beats per minute as recommended by Lou Fournier in program four. He states that music played at this rate slows brain wave patterns, is very relaxing, and increases retention (Laureate Education, Inc., 2002). In conclusion, using the many features of PowerPoint can enhance a presentation so that it is better received by the audience..  DNA: Blueprint of Life

  10. Jamie McKenzie author of the article, “Scoring Power Points,” states that the best presentation “enhance and communicate a larger and deeper body of work and thought” (McKenzie, J., 2007). Multimedia presentations are a great way for teachers to draw their students into the lesson and keep them enthralled from start to finish DNA: Blueprint of Life
