Description
In this section, I talk about changes to DNA Sequence, a.k.a Mutations. Mutations can lead to some significant problems, but in some cases, they can also lead to a trait that is beneficial to an organism, helping it better survive in its particular environment. There are different types of mutations, and these different types vary in how much of a difference they can make in an organism’s genetic code. Any change to the genetic code can result in a change in the proteins, which can result in a significant change in an organism’s traits.
Fortunately, there are some mechanisms in place to minimize spontaneous mutations, and I also talk about these things in this section.
This is part Chapter 11 in the textbook Biology: The Dynamics of Life, which is the chapter on DNA and Genes.

THANK YOU SO MUCH! I have been worrying about passing Biology for the entire year due to a bad teacher and a noisy class, and you have just seriously SAVED me from getting a bad grade. Thank you thank you thank you!!!!
You are VERY MUCH WELCOME Lenette. So glad to know that the videos are helping you so much. All the best with your class. Let me know how it goes 😀
Unable to view videos for Chapters 10 and 11. The videos I’ve seen so far were so helpful because I was able to understand the material. Am I doing something wrong? I’ve tried going through dashboard. Clicking on the link does not work.
