Video: DNA, the Molecule of Heredity


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.
