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!

The DNA and Genes Game

So you think you understand DNA and Genes? You say you know how the process of transcription works? Yeah yeah, you even understand translation, and you are an expert on Mutations because you’ve watched X-Men ten times. Go ahead and test your knowledge by playing the DNA and Genes Game. Go on, I dear ya!

Description

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.

Transcription is the process that results in the production of mRNA. Translation ultimately results in the production of proteins. Understanding these to processes is essential to our understanding of how DNA is the Blueprint of Life.

This is part Chapter 11 in the textbook Biology: The Dynamics of Life, which is the chapter on DNA and Genes.
