DNA single point mutations

[multizeroMr]

U in DNA strand?!

[gkpeter]

@multizeroMr I think I made a mistake, but fixed it ages ago.

[iranianboy123]

wow, explained it better then textbook and teacher

[TheYazzola]

leucine is uug not uua

[gkpeter]

@TheYazzola Leucine can be uua,uug,cuu,cuc,cua, and cug

[TheYazzola]

@gkpeter thx alot for the info i was reading my book so i got confused thx again :)

[TheScarletteyes]

@TheYazzola the codon table shows it is either UUA OR UUG. :)

[craigm88]

5:45 shouldn't that be T instead of U because it is DNA?

your videos are always 10X more easy to understand than my professor. Please keep posting more videos, you are a very big help in terms of my understanding of genetics. Thank you very much!!!!!!

[angelitapatti]

whoa thanks!im watching it now as a revision to mutations test im having tomorrow and i have to say dis vid is very gd!

[chigachigayeah]

thank you so much,

helped me a whole lot on my bio hw!

[jioo129]

You explain so clearly that even my little niece can understand this.

[rahed53]

great video, thanks for the explanation

[davidkeys100]

Fantastic comprehensive explanation. I was confused as to weather mutations occured in the DNA itself or if they were a product of "mis-copied" section(s) or additions of nucleotides base pairs. This irons out a lot of wrinkles.

[salvations101]

Sorry, thanks for your time. Truthfully, I don't think probability would allow mutations to explain evolution. It is difficult to find anyone to debate that. Have a good day and keep up the science.

[gkpeter]

@salvations101 No problem. There are a number of sites online to debate this material. I don't think you are going to find legitimate places to debate on YouTube. There are a number of scientific blogs that may be useful.

@salvations101 mutations can change a species phenotype. Over millions and millions of years these changes can form a new species if the environment prefers the mutation over the wildtype. We can see evolution happen before our eyes through plating bacteria since they have such quick life spans. They develop different resistance depending on the environment they are grown in!

[salvations101]

i wish there were someplace i could discuss this. i just don't see the probability of mutations explaining evolution. sorry.

[gkpeter]

@salvations101 I don't know how good it is, but try evcforum.net

[salvations101]

in macroevolution, could you give me the names of two entirely separate species, one of which evolved from the other?

[gkpeter]

@salvations101 Sorry, this is not the place to debate evolution. It is just a video describing mutations. Thank you.

[RespectMyHate]

so mutations created eyes, ears, tastebuds, hearts, brains, blood vessels, human beings?

[eternallegend2007]

thanku so much! :)

[MirrorImage17]

good job! you explained it pretty well! I'm gonna write my graduation exam in Biology tomorrow & this helped a lot! (btw I'm german, but in a bilingual skl ;D)

[salvations101]

do these mutations support macroevolution or microevolution?

[gkpeter]

@salvations101 both

[salvations101]

does this info line up more with an evolutionary point of view or a creationist point of view?

[gkpeter]

@salvations101 evolutionary

[AlexaCaius]

Excellent video, very clear to understand and makes point mutation so much easier to get my head around in terms of what each mutation is labelled. Thank you for posting this. Do you have a video on chromosomal mutations (translocation etc)?

[gkpeter]

@AlexaCaius I do not have a video on that yet.

[arteta0425]

ty, now where is frame shift! :)

[2funkeyme]

thanks....

[achmed07]

um i think u got the codogene dna template wrong (5:48). there's no uracil in the dna. so the dna template for UUA would be AAT.

[gkpeter]

You're right, I will annotate it later. Thanks!!

[coffeeandsocks]

Thanks!! That was brilliant!!
