I'm in uni now and I felt like I'm behind cause the teacher said this was stuff everyone knew. I couldn't wrap my head around it, but now I understand everything; thanks to you.
I've been in school for approximately 573 years, and in all of my time this has been the most concise and intelligible explanation of these strands. Thank you. -Rip van Winkle
So, are there any teachers here? Happy you're okay with saying 'i don't know'. I love these kind of teachers. Everyone does. Teachers need to work on themselves! With due respect to you all. You guyz are teaching us please TEACH for the sake of TEACHING!
So basically DNA has evolved from RNA with chemical modifications and DNA is more stable than RNA (As RNA being a catalyst is reactive and unstable. And RNA is unstable due to the 2' OH group present at every nucleotide) So since DNA has evolved from RNA it is better, more stable and it also has a complementary strand as it further resists changes by evolving a process of repair. (PS : I am still a student and I've written this answer based on what I've studied and understood from my Text book. So please excuse me if I've made any mistakes)
that is if one strand is considered from a-b then the other is b-a.... given that you start noticing them from the same position... say the top.... in pother words if you start from the top of a DNA helix holding it vertically, then one strand starts with a and ends at b and the other strand starts at b and ends at a... i hope this helps
Not only taught why there was "antiparallel DNA strands" but also " nitrogenous bases " in the lesson named only " Antiparallel DNA strands " , they didn't belong to each others , but maybe short name of lesson is better !

I finally understand this after having been confused in my biology classes for 5 years lmao thank you so much

If all teachers could explain the 3'->5' like this, the world would be a better place lol
this is the only video I found that actually made me understand it. Thank you
Thank you sal khan.May allah give you the best in return.
Your channel gives me motivation to become a doctor.
Had a delicious "Aha!" moment watching this video!
Finally understood Thank you
Its still surprising life became sentient with beginnings like this.
You are a great teacher 👍

thank you so much!! this is actually really interesting and makes sense to me now :)
Thank you, thank you, thank you!
Khan academy you are the king of teaching!
Thank you a bunch!
bless you
You are a GREAT TEACHER!!!
Sal is literally the best
After two years of my study I am now finally able to understand why didn't I get this earlier
Exactly what I needed. Can't thank you enough Salman sir!
But what is the reason for the strands running in antiparallel as opposed to parallel? Like what is the benefit or the reason for this to happen?

@@nidhishakakarla6921so why is RNA antiparallel
I really appreciate your work sir . and i have watched your TED X talk on this topic . You are just amazing .
Very helpful illustration, thank you
Thankyou so much! I finally understand this now!!
6:14 shouldn't there be another hydrogen attached to C4' ?
Nice vid
thumps up definitely!
khan academy exists
me:
i am saved
Waht is meant by dna strands are antiparallel?
that is if one strand is considered from a-b then the other is b-a.... given that you start noticing them from the same position... say the top.... in pother words if you start from the top of a DNA helix holding it vertically, then one strand starts with a and ends at b and the other strand starts at b and ends at a... i hope this helps
why are the strands antiparallel??
because they wouldn't conform otherwise (A would not pair with T, C would not pair with G)
rachel brawn Thanks for info :)
One strand is in 5’ to 3’ direction the other is in 3’to 5’
Not only taught why there was "antiparallel DNA strands" but also " nitrogenous bases " in the lesson named only " Antiparallel DNA strands " , they didn't belong to each others , but maybe short name of lesson is better !
