Read moreDNA 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.
Read moreDeoxyribonucleic 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.
Read moreSo you’ve been studying about Mendel and Meiosis. You went through Presentation and probably even watched the the lecture videos. Now it’s time to test your knowledge with this fun version of the game Deal or no Deal. However, this game is Grade or no Grade. No Million dollars but a lot of fun, while learning.
Read moreMeiosis is a process that body cells undergo that results in the production of gametes (sex cells). The male gamete is the sperm and the female gamete is the egg. When a cell undergoes meiosis, the end result is 4 gametes, with half as much genetic information (haploid). In this section, I talk about Chromosomes and genes and how the process of Meiosis plays a vital role in living things. I also go through the steps of Meiosis in some detail.
At the end, I talk about mistakes that can happen in Meiosis and how this can either lead to significant problems or (in some cases) benefits, depending on the organism involved.
Read moreThis is the handout for chapter on Mendel and Meiosis. There are three slides on each page, with enough room for you to take extra notes. Some of the words are omitted and you can fill them in by watching the presentation for this chapter or one of the videos for chapter 10. You can download it as a pdf and print it. Just go ahead and click on the Download or Print link that’s right above the handout and you should be good to go.
