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?? :))
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
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.
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
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?
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.
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?
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"?
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!! :)
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.
it does make a difference if you go from Purine (Either A or G) to a a pyrimidine (T(u) or C) and vice versa. The reason has to do with the number of rings associated with the bases. If you go from a purine to purine or pyridine to pyrimidine, you don't see a difference in the amino acid. So going from U to C, does not affect it as you're going from a pyrimidine to a pyrimidine and the same thing applies to going from A to G.

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 RUclips!!! 😊
Me
its meh
You are a master at explaining this. I'm in awe of what I just learned in 10 minutes. Thank you so much!
am literally preparing for my Biotechnology exams tomorrow, great explanation
The Boston or New Yorker Accent is strong with this one in her O’s and A’s
just watched this 10 min before my exam n all the anxiety is gone thanks 🙏
Thanks! This helped immensely in understanding DNA redundancy.

This Lady is very excellent 👏👏👏👏
This has been so helpful, thank you greatly
thank you so much!!! so helpful i study biology in arabic but this helped me alot i have quiz tomorrow
the best explanation so far👍
Immensely helpful. Thank you so much !!!
Great Explanation, I can use it for our lessons, thanks!
loved it though
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
Amazing! Thanks a lot.
thank you am saved by your teaching
It's all been written. Let no one fool you. WAKE UP ruclips.net/video/CfFNaqoSWUA/видео.html

Newfie-Dean thank you for that!
Carly Fisher glad to help!
absolutely beautiful explanation. Keep it up :D
Excellent presentation. Thx.
thnkuuuu...this helped me a lot.....
degenerate, basically a fancy term for redundant....XD I love it

I love you 😭😭 you made this so easy
Much Gratitude. Magical Miracles Radiant Souls
Superbbb😚
Omg this helped me so muchhh thank youuuu
Just amazing
This is very helpful shout out KA!!!!!!!
Thank you, I needed this.
Thank you!
Great video
Amazing lecture.. I wonder who those 16 people are who disliked the video.. It's so awesome who would dislike it.
अति उत्तम अध्यापनं ।

thanks God i love want this video becos tomorrow we will have exam
شكرااااا thanx 😍😍😍😍
thank you. good explanation !!!!!!!
very cool - thank you!
thanks!
Thankssssss ❤❤❤❤
awesome mam thank u
Thanks a lot!
which platform do yall use, if possible let me know :)
Amazing 💌👏👏
*BRILLIANT MA'AM*
well explained, tnx
Thanks 👍
really helpful

What you writing on screen I can't see it properly
Thank you sooooo much
Where is genetic code restored? Thank you
thanks ❤️ ساعدني الشرح كثيرا على الفهم
Great video tnx a lot
thank you so much
Fantastic
❤ that great thank you
I just can't believe is so freaking simple.
🤣🤣
Lol
Thank you!! :-)
can someone tell me what her accent is? i'm not from america so i can't work out what it is exactly
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
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.

At 5:23, sirens can be heard. A lot of them.
thanks alot
nice video
Yeah...It's helpful ...😃
How do you find the corresponding codon when you are only given the amino acid?
Thanks !
Wow! DNA is smart!
Ty❤soo much
u wanna hijack my skeleton? DNA is what makes "YOU", you.
Did you act in YOU web series of NETFLIX? Because the voice reminds me of a character in it!
why incomplete? btw thanks
genetic code beautifully explained from basics
Very good, but I can't see what you're writing!
exactly...
thanks
That's amazing
So adding adenine at the end of each codon ends the translation process?
perfection
Thankyou
but on what signals does the strand get picked for transcription?
lel where are you from? once in a while your accent gets really thick
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
Did anyone else hear police sirens at 5:40?
I LOVE IT
Why starting codon Met (AUG) is not degenerated so as for Trp (UGG)??!
Met is coded only by AUG
i fucking love the genetic code
+Brendan Richardson fuck bio
Not sure why all the hard language lol
you fucking serious
super
the best

Genetic coding in Haskel?
ohh.wow.great!!!!!
Why do some codons have 'Y' in them? E.g. CGY
Amino acids full form give me pls
Intelligent design anyone??? and the Universal aspect proves one designer.
isnt it meant to 'U' instead of 'A'
Weird how the third letter in the codon sequence doesn't really make a difference, it's mostly the same amino acid if the first two letters are same
nevermind, it only works for U and C in the second letter of genetic code
it does make a difference if you go from Purine (Either A or G) to a a pyrimidine (T(u) or C) and vice versa. The reason has to do with the number of rings associated with the bases. If you go from a purine to purine or pyridine to pyrimidine, you don't see a difference in the amino acid. So going from U to C, does not affect it as you're going from a pyrimidine to a pyrimidine and the same thing applies to going from A to G.
Melat Worku that makes sense, thank you.
