Codons and the amino acids they code for is represented by standard charts can be found in the public domain. While the rectangle chart is the common format, there may be other ways to represent the information. P.S.

We like to pin comments for clarifications when they are needed. At the point where "random" is mentioned in the video, it is discussing the effect of whether the mutation is beneficial to the organism – this is why we follow the sentence with, "The organism can't will itself to get a certain mutation." We chose to address this, because it's important to understand organisms are not "choosing their mutations to adapt and evolve" – a frequent misconception. An additional, lengthier source from Berkeley that also explains "random" in regards to mutations is here: https://evolution.berkeley.edu/evolibrary/article/0_0_0/mutations_07 But this is different than the mutation rate or frequency which can be altered by both external and internal factors (we actually mention some at 1:38 ). To read more about this, we found a great further reading article from Nature Education – you can scroll down to their answer "Are Mutations Random?" https://www.nature.com/scitable/topicpage/genetic-mutation-1127/
Just a note: in case you've seen our old mutations video, this is an updated form. The script is nearly the same, although we think we improved explaining a silent mutation and a frameshift mutation. We also emphasized that mutations can happen in all kinds of organisms (and viruses too)! Our art has also improved as we continue to practice. No MS Paint this time ≧◡≦! You can see our milestones here: https://www.amoebasisters.com/milestones We did decide to create an updated free student mutation handout—we don't always update old video handouts, but we wanted to improve it: https://www.amoebasisters.com/handouts Still prefer the old video (and handout)? No worries! We try to not delete old videos and you can find it here: https://youtu.be/GieZ3pk9YVo
I'm an adult yet I watched it because curiosity
my bio teachers assigns your videos as part of our modules. so much better than reading
where do you get genetic info, when fish turns to a frog? how does the dna change or add?
Thankyou for this video
Really helpful 👍
This channel is the most amazing channel I ever seen…
Those things or topics which are not easy to understand…
This video will help you alot…
Through animations and by expression of the cartoons 😂😂😂in this video makes easy learning. As well as interesting 😌😌😌
this channel is so unnecessarily helpful, im a sophomore in college and i literally rely on these videos for my labs
Hello! I'm Vietnamese. I'm 17 years old. I really happy to see and watch your videos. These makes me learn biology by heart easier and faster. Hope you can make more interesting videos like this <3 <3
the vibe when u just watch amoeba sisters and call it studying
Hi from online learning team 👋
thanks for the sweet video!
Dear and wise Amoeba Sisters you've become my favorite source of bio info. You talk in such a clear and concise way, and the funny and amusing illustrations accompanying your explanations put a smile on my face. You truly excel at that and gives your videos a plus. Many thanks and Congratulations!!! 🙂
Video on hemoglobin plis 🥺
i have a bio quiz on this tomorrow, wish me luck bc i havent gotten above a 75 on any of my quizes/tests this year😭
No one cares about your childhood just give us the lesson please.😂😃
im watching from switzerland and thanks to you guys i have an A. you guys are a gift and i’m so thankful. i really want to thank you because every time i have a test or an exam you help me. thank you so so so so so much <3
Thank you. Thats great. I hope you add the Arabic subtitles.
This vidoe was exactly the same with our biology lesson in school
I'm medical student rn and still watch your videos 😅
We now know that mutations are not random, and all of that was wrong.
Experiments with flys showed that mutation isn't random. It's greatly influenced by the environment. Specificly information recorded by the parents bodies about the environment at point of conseption. Too hot, too cold, not enough food extra, experiments have show organisms mutate benfitial traits too quickly for it to be randome. And explaining the diversity we see with just natural selection is like trying to preform surgery with a sword. The theory lacks the fineness to do it alone.
I always though it didn't quite fit so am great ful for these breakthroughs. Any lingering questions I had about evolution have been answered. It's a pretty important breakthrough. Maybe another update is needed?
saving me before the test tmr
Is Mutation a good thing? Yes or no? Why or why not?
