DNA mutations made simple!

This video will cover nonsense, missense, frame shift, wild type, insertions, deletions, and duplications in the genetic code. DNA codon basics, wobble, and how to interpret DNA code mutations will be covered!

[@berniedmjm4108]

Correction! You are partially correct about MISSENSE mutation. Partially correct because a letter does change but the ending result about the amino acid not changing... It DOES change the AMINO ACID. It can be something else other than histidine. Silent mutation should be part of your bullet points since you described it. Silent mutation DOESNT change the AMINO ACID.

Great video, thanks 😊

[@ScienceAnswers101]

Thanks for the feedback!!!!

[@MagmaWoodworks]

In your example for duplication, shouldn't the first codon be UUA and then a duplicated UUA? Since UAA is a stop codon, this example is actually a nonsense mutation instead of a duplication since all codons following the first UAA will be ignored until a start codon is encountered.

[@maddnee]

on the last mutation ( duplication ) you wrote two stop codons in a row, instead of UUA UUA

[@libanish]

Changing the third base (rightmost) in a codon is actually a SILENT mutation, and not a missense mutation. Codon will still specify for same amino acid, due to wobble rule of codon-anticodon pairing. Missense mutation occurs when 1st or 2nd base in a codon changes into another base, forming a new codon that specifies for another type of amino acid.

Thank you, I like your analogy!

[@jameskennardsanzjacob9675]

Is 7:34 correct?

[@psycho_fox]

silent and missense are two different mutations

[@hadizajibril5428]

thanks alot got finals to write on friday,you just saved me!!

[@DA-sj2gw]

CAC is not missense (there is no change in amino acid sequence). Its a silent mutation (no effect on protein) ? 7.34

[@dorianl.210]

Missense and silent are mutually exclusive i Beleive. If Missense then amino acid was changed by nucleotide change, if silent than despite nucelotide change the amino acid was not changed (because of degeneracy).

at 1:01 did you mean to say UGA?:

[@jacquanhilliard]

Thanks for the video!!! , it help out alot while reviewing for my genetics exam

[@dr.humayunkabir742]

Are A,T,G,C representing neucleotides? or purine/pyrimidine bases?

[@shaunaklavande8159]

+dr.humayun Kabir nucleotides I'm pretty sure.

[@rainbowcolours3544]

Purines and Pyrimidines are nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA. The two-carbon nitrogen ring bases (adenine 'A' and guanine 'G') are purines, while the one-carbon nitrogen ring bases (thymine 'T', Uracil 'U' and cytosine 'C') are pyrimidines. ^_^ Hope this explanation is helpful. :) Good day.

Thank you so much got GRE subject test tomorrow :(

[@alexiacase6732]

thanks for making it so simple!

[@umanghayat9721]

You are brilliant!!!

[@sincerelycali]

OMG thank you!

[@hxarsh001]

Very goooooood...... Thank you ...

[@20yearsofBoredom]

Thank you! Finally it made sense! :D

[@Lovemypiano1]

THANK YOU VERY MUCH

[@waleedtaher2012]

very helpful. Thanks

[@celaenas3016]

i hate studying genetics

[@natthamuffin5113]

I hate this shit too- I’m failing bio

[@saraj233]

Thank you!!!!

[@roaahashim9373]

much love 💗

[@vladimirospeilivanidis8621]

aren't these mRNA codes and not DNA?

[@djshuey]

thanks this is very simple and easy to understand

[@rajan-tarunofficial9264]

thank you for your

[@amanksingh04]

thanks alot

[@gemmacareyxx2620]

Sound like Gabe from the office

[@friendsfamilyguytheoffice9633]

awsome (Y)

[@kimdrkim]

this has a number of error.

[@kimdrkim]

RNA has the nucleotides AUGC, not DNA... DNA does not 'read' codons.... Ribosomes bind to mRNA at codons where tRNA binds with its complimentary anti-codon...

[@kimdrkim]

Insertions and deletions ARE FRAMESHIFT mutations... they both ruin the reading frame for the entire length of the sequence thereafter... this is going to give students a lot of incorrect information... please edit this to correct the issues.
