Mutations: The Potential Power of a Small Change
The Amoeba Sisters discuss gene and chromosome mutations and explore the significance of these changes. Music used with permission from Adrian Holovaty (http://www.youtube.com/adrianholovaty). This video has a handout here: http://www.amoebasisters.com/handouts.html
We appreciate the feedback we get for clarification or improvements on our videos. At 2:11, we try make the A (adenine) base look upset now that the complementary base T (thymine) has been replaced with a G (guanine) in a point mutation. But we wish we had put more distance between the cartoon bases to clarify, that now, they cannot bond in this way. Note: This can sometimes be fixed by a polymerase in proofreading- but if not fixed- the G may be be matched with a C and the mutation will remain.

The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky’s certification and experience in teaching science at the high school level. Pinky’s teacher certification is in grades 4-8 science and 8-12 composite science (encompassing biology, chemistry, and physics). Amoeba Sisters videos only cover concepts that Pinky is certified to teach, and they focus on her specialty: secondary life science.

We cover the basics in biology concepts at the secondary level. If you are looking to discover more about biology and go into depth beyond these basics, our recommended reference is the FREE, peer reviewed, open source OpenStax biology textbook: https://openstax.org/details/books/biology
