Mutations

Paul Andersen describes the major mutations found in the living world. He starts with an analogy comparing the information in DNA with the information in a recipe. Changes in the DNA can result in changes to the protein, like changes in the recipe can result in changes in the food. He describes the three major point mutations; substitutions, deletions and insertions. He also describes several chromosomal mutations.

You're a better teacher than my actual bio teacher, he just sends us over here and then gives us worksheets.

Mr Andersen, im in 1st year med school..you have become part of my family..part of my daily routine..THANK YOU!

ever since high school no one could ever explain to me how a point mutation on one strand affects the other strand of the DNA molecule. i'm now 26 years old and thanks to you i FINALLY understand. your videos about light waves and optics also helped me a ton; i'm currently studying for the MCAT. thank you so much for doing what you do. your videos are even better than Khan Academy's.

Great question. All life is connected back to the first life forms through our genetic material. Therefore the entire diversity of life on our planet was created through mutation (and genetic recombination).

However if you are looking for simple "good" mutations in humans here is a start: lactose persistence, malaria resistance, the ccr5-Δ32 mutation that gives HIV-1 resistance, and my personal favorite tetrachromatic vision.

Mutations include mind control, the extension of claws, ice creation, manipulating metal, changing form, controlling the weather, firing energy beams with your eyes, traveling at supersonic speeds, able to tell which movie I'm referring to, and multiplying yourself.

I have a test in half an hour and this helped me understand the lesson better than what my teacher has tried to teach us in a span of a month. Thank you!!

I learned more in one video than my teacher explaining this lesson in an hour and a half, thank you!!!

[kellyannkoerner]

Your videos have taken my college biology grade from a C- to an A. I am so grateful for your work!

[maryadel]

Your videos are amazing. You don't know how much you've helped me. I went from a C to an A+ and from a 70% to a 105% I just wanna say thank you so so much you're such a great teacher.

[alexanderwyne]

Thank you very much. i just finished my exams, and the subject was mutations. i used some of your work, and i got an A+! Thank you very much for this simple and informative video. :)

[MrBlash]

You are a very talented educator. Thank you very much for making this video. You really helped me.

[alexiacase]

"and i hope thats helpful" yes every word you say is so damn helpful. You are amazing and I am so thankful for your videos. Keep rocking Paul Andersen. You are so important thank you for saving me for literally years now.

[emilyd]

Currently studying for my Biology Test and Exam.. Thank you from me and the rest of my Year 12 Class, for taking the time to make these videos! :)

the nestle chocolate chip cookie recipe is actually a godsend

At first glance, I thought Mr. Anderson was Hank Green...

[myrmibarra]

This actually made way more sense then how my teacher taught us it

[falon]

You are a legend. Thanks for uploading these videos! Helps a lot!

You are a best teacher for genetics. 👍
