This is a great short, to the point presentation. My only suggestion is to show visually what is occurring when explaining what is occurring with the genes 🧬 so we can better comprehend and see exactly what is occurring rather than only comprehending it on a theoretical level.

[Starrynight]

yeah, but what causes these mutations to happen? This explains how they happen. Why does the shift suddenly occur? Why the split, etc?

[pakistanschoolmuscat]

Thanks a lot..mashaAllah you clarify the concept very well

[HBCTXIntro]

excellent presentation, however the heading should be 'mechanism of gene mutations' an not 'causes of..'. There are many theories for 'causes' which are not well established yet.

[ghr.a]

i think you are the best tutor in khan academy.. thank you so much.

[masudanasir]

wow, what a nice presentation, you explained it very well, more especially how you provided a summary at the end.

[JoLaffar]

What mutations are more likely to happen when reaching adult age due to environmental factors, chromosome or genes mutations? Thanks

[painfullyhonest]

I'm in a conversation with a friend who says that a person's emotional state or physiology is not a factor in point or shift mutations. That psychology does not have an impact on mutations at all is that true ? have there ever been any clinical studies on where or why the mutations occur? Is there a psychological emotional or mental aspect to these anomalies?

[kimmieb]

Help... Can you describe the mutation in the DNA? 2. Please describe the change it caused in the mRNA and 3. Please explain the change in the protein. Thanks.

[iwa-chann]

This is for an assignment, but can you explain how mutations can occur during replication?

[lnz]

This is how it mutate. Please make a video of factors that might cause this to happen. Thanks

[akagerhard]

Do you believe these causes are strictly random, or do you believe there are non-random aspects to what kind of mutations are more likely to occur?

[pakistanschoolmuscat]

Does Large scale mutation effect gene expression in addition to effect on protien synthesis?or either one of the two

[jackster]

could we in theory create new species by changing the DNA structure of any organism?

[moranMB]

I think that the video explains HOW but not WHAT causes mutacion.. so it's not talking about causes.

[menosproblemos]

12tone (youtube channel) all does a neat
Seeing the point while hearing the point is a good way to follow the logic.

Check im out! Maybe get a tip?

[klaymistic]

You’re basically explaining what is mutations are, but not what causes them

[alpetterson]

You don't seem to be talking about the causes at all. You explain the HOW and not the WHY.

[ValMar]

I lost it after 1 minute 😩 I am definitely not smart

God is the greatest programmer in existance.
