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

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.

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!

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?

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)

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 !

Waht is meant by dna strands are antiparallel?
@riddhidutta5601

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

One strand is in 5’ to 3’ direction the other is in 3’to 5’
