The genetic code

[@ildikoschmutzer1322]

Don't you just love it when a less than 10min video teaches you what your teacher hasn't managed to teach you for a WHOLE SEMESTER :)) I am lowkey so mad right now, this whole thing about translating mRNA stressed me tf out for MONTHS, giving me so much anxiety and now you're telling me that all it took was just ignoring my teacher and watching a youtube video?? :))

[@reddasher3061]

I call Bullshit on that one LMAO.

You get very easily from Khan sir ac. Coz u come here after a struggle in understanding the topic and during the struggle u unconsciously get some idea about the topic and when u watch video ur brain learns fast ⏩

UNIVERSALITY OF THE CODE - Initially the genetic code was believed to apply universally, that is all organisms would recognize individual codons as the same amino acids. However, it has now been shown that some variation in the code exists, although this is rare. For example, animal mitochondria have a small DNA genome containing about 20 genes in which deviations from the genetic code occur. Changes are mostly associated with start and stop codons. For example, UGA, which is normally a termination codon, codes for tryptophan, whereas AGA and AGG, which normally encode arginine, are termination codons, and AUA, normally isoleucine, specifi es methionine. It is thought that these changes tend to be viable because the mitochondrion is a closed system. A few examples of nonstandard codon usage have now been found outside mitochondrial genomes in unicellular organisms. For example UAA and UAG, which are normally stop codons, encode glutamic acid in some protozoa. SOURCE: Genetics, Hugh L. Fletcher, ‎G. Ivor Hickey - 2013

Who else here is trying to learn on their own since schools are closed coz of COVID-19🙋

That's the most beautiful comment I've ever seen on KZbin!!! 😊

You are a master at explaining this. I'm in awe of what I just learned in 10 minutes. Thank you so much!

[@mahmoudabdulbaset5452]

I think there should be more details to link information together it’s not right just to go on without the main basics of the lesson but thank you it kinda helped me

[@MrMahenyl]

Thanks! This helped immensely in understanding DNA redundancy.

[@werkatfischer3183]

Noncoding DNA can actually still play a big part in gene regulation since the length of LINEs/SINEs/STRs can affect the rate at which coding regions are transcribed, as well as affecting the structure of chromatin and where genes are activated.

[@andrewdelacruz6715]

Great Explanation, I can use it for our lessons, thanks! loved it though

[@connorghita4245]

This has been so helpful, thank you greatly

[@ushmagill6721]

the best explanation so far👍

[@akhan3595]

Great explaining! It's easier than I thought.

[@selenagomez9915]

[@maheerkhan8500]

Amazing lecture.. I wonder who those 16 people are who disliked the video.. It's so awesome who would dislike it.

[@midosala8049]

Amazing! Thanks a lot.

[@carlygrace7823]

That was very helpful. I understood that well. Now I know the base to start at. But my question is “ explain that variations in trait are caused by variations in the genetic code” I feel like I understand that, but is there another video y’all recommend to further learn?

[@newfie-dean5803]

Carly Fisher the DNA is made up of many genes all of varying lengths. Some genes might have a sequence that contains 150 nucleotides in length. Other genes might have 1 million nucleotides in the sequence. It is the variation of nucleotide sequencing within a given gene that results in different traits. Here’s a simplified example. Maybe you have ACGTAC as a sequence in a hair gene that gives a person brown hair but in another hair gene you have ATGCAC which gives the person black hair. What genes you have to begin with are determined by what was passed to you from your parents.

[@carlygrace7823]

Newfie-Dean thank you for that!

[@newfie-dean5803]

really helpful

[@d.improver]

Thank you, I needed this.

[@dustinshutson]

How were the codons assigned to their amino acids? It's my understanding that the order of the nucleotides doesn't release an enzyme or anything that could possibly link codons with their specific amino acid. So how is the code being "read"?

[@Sophia-rq5ir]

thank you so much

How do you find the corresponding codon when you are only given the amino acid?

I'm not american either but if I had to guess I would say somewhere in New England, like New York/Massachusetts/New Jersey, that kinda area

[@devarikadraallu5200]

super

[@the_larsonfamily]

That's amazing

[@realorainecruz4643]

So adding adenine at the end of each codon ends the translation process?

[@mariannerimando]

ik how to code rna codons i just dont know how to code dna and where to start it cant be just random base pairings

[@erikvoitus7488]

Why are Chromosomes almost always showen in the distinct X shape, which is only shaped like that after duplication. i mean most of the time Chromosomes are just lines with a centromere. when you depict it as an X shape you confuse students who need to know and sketch meiosis and mitosis.

[@hpspspspsps5798]

but on what signals does the strand get picked for transcription?

Anyone else hearing the siren in the background? 😅

I may be the only person that noticed this, but are there crickets in the background? you may not hear them at first, but I started hearing them around 3:20. Sorry if it seems a bit disrespectful to point out, (not saying that it's a problem, I only noticed it because I watched the video for about 30 minutes) but thank you for making this video, it helped me out a lot!! :)

[@jamesnite2157]

Why do some codons have 'Y' in them? E.g. CGY

[@navabhaidamor2603]

Amino acids full form give me pls

[@Minmin_Chan_2018]

Why starting codon Met (AUG) is not degenerated so as for Trp (UGG)??!

[@tellau]

Met is coded only by AUG

[@saewonyi]

I look at the genetic code and I immediately would conclude its function was made by an intelligent force. This looks like computer software and I would never argue a computer program, no matter how many billions of years you give it, would randomly code life. Just thinking how long some of the code would be for complex functions, it just will randomly happen if you give it enough time? To me, that requires more of a leap of faith than believing an intelligent mind coded it. And the fact that theres a stop function, doesnt that require intelligence? Why would a random genetic code randomly throw in stop in its code? Doesnt stop imply intent which then obviously implies intelligence?
