Description
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.

Hello Leslie,
I’m trying to watch the video for DNA, and it is not loading?
What do I need to do.

Sorry about that. There were a few issues with the transfer to the new server. Working on re-uploading the videos now.
Hi,

Sorry about that inconvenience. I’ve finally fixed the issue and you can watch the video now.
The video is still not working.
It’s working for me.
Hi Leslie,
I am a straight A’s 4th year psychology student – hoping to go to grad school next year. I am currently 4 weeks into a course called “Biological Basis of Behavior” and you have quite literally saved my GPA from suffering a severe blow. Sadly, my professor is dreadfully unenthusiastic and and dry about the subject and I was feeling like I had to teach myself the entire course just to get through it. I have watched every single one of your videos on the nervous system, (and some others too), and thanks to you I now have MUCH better understanding of my course material. I have read my textbook closely, but you have clarified so many things for me with your simple way of explaining things and your visual demonstrations. Sorry to gush like this, but I really am SO incredibly grateful to you.
First, and most importantly… I LOVE you.
Thank you.
Carol
LOL, thanks for your love Carol
So glad to hear that the videos have helped you. Comments like that motivate me to continue doing what I’m doing. Stay tuned for more, because I have lots more coming. We’re working behind the scenes to make Interactive Biology even better.
All the best!
