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!

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!

Deoxyribonucleic Acid – You know, the word that everyone likes to say. The blueprint of all living organism that controls every trait that an organism expresses. It makes you who you are, because it is the foundation of who you are. In this lecture, I talk about the structure of DNA. It is a polymer that is made up of subunits called nucleotides. DNA controls our traits through the production of protein and these proteins are responsible for all functions of life.

Lastly, I talk about DNA replication, because in order for cells to go through mitosis or meiosis, DNA replication has to happen. DNA polymerase is an essential enzyme in this process, and I end the lecture by talking about how DNA polymerase does what it does. Enjoy!

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