McDonald’s, Wendy’s, Olive Garden and China Garden – they all have something in common, they all serve FOOD. But all foods are not created equally. I you want to be healthy, you want to make sure that you are getting what you need. In this lecture, I talk about nutrition, starting with the 6 vital nutrients and where you ind them and how your body deals with those nutrients.

I end the section by talking about Calories and metabolism. What determines how many calories we need on a daily basis? Watch the video to find out.

Chapter 11 Presentation – DNA and Genes

By on February 18, 2010   /   Biology 1, Powerpoint Slides   /   Leave a comment

These are the actual presentation slides for Chapter 11 in Biology, The Dynamics of Life. You can go through it at your own pace and learn about the wonders of DNA, how this Blueprint results in the production of proteins, and how that results in an organism’s traits. It also covers the topic of Mutations. It’s amazing to think that inside each cell, as tiny as they are, you can find the information that results in all of this complexity that we see. Enjoy!

Video: From DNA to Protein

By on February 5, 2010   /   Biology 1, Genetics, Video Lectures   /   4 Comments

DNA is expressed and put into action through proteins. These proteins are involved in structural support and they also act as enzymes. Enzymes are involved in all of the chemical reactions that happen in the body. In this lecture, I first talk about the relationship between DNA and Protein and how this relationship leads to all of the traits that an organism expresses. I then go into the differences between DNA and RNA.
