DNA | it's structure | NCERT | explained in Hindi | simple words

So today we're diving into a very important topic About DNA What is DNA and what is its structure like The DNA we refer to is Deoxyribonucleic Acid What is this It is a molecule that exists within our body Inside every organism lies a certain molecule and it is precisely this molecule that makes life possible You have no height you have no color Do you have any color in your hair What is your skin tone like Your hair has been cut so it won't grow any longer So now we look at its structure What DNA is made of And how is it made Dane is made up of three basic things One is Sugar one is Phosphate and one is Nitrogenous Base Sugar contains deoxyribose and phosphate groups and nitrogenous bases are present in it Adenine Thymine Cytosine and Guanine Which we also refer to as A T G and C We can further classify them into purines and pyrimidines Purines include adenine and guanine Cytosine and thymine are found in pyrimidine And together all these elements form the structure of de Yene's case The back-bund that forms from the Deyene area It becomes what we have—phosphate and sugar Phosphate and sugar together will fuel our D yen And it is responsible for joining together the two backbones The nitrogenous bases we have are Together these two form the complete DNA helix What we have on our side is sugar a phosphate group and nitrogenous bases Together we can say: a nucleotide is a nucleotide And the nucleotides present in DNA are So what do we call this entire chain Polynitrate chain they say Because it contains numerous nickel particles interacting with one another What happened We're all set after this we'll read it The model developed by Watson and Frikk has achieved significant advancements in natural language processing So what exactly had those two said What exactly is Alex's problem The two strands we have are intertwined with each other They are entwined clinging to each other like doves And this coiling here is the right headlight And how was this confirmed One thing is confirmed: Roslin Franklin and Maurice Wilkins' X-ray diffraction data via Whenever we look at Dene's structure It's already turned And their length will be ree point four nanometer that is 34 angstroms in tur Between the first turn and the second tur After that we will read about base pairing The rules that Churgraf had provided Whenever anyone comes to us from Adenine If it happens he'll go and join up with Thaimin And if cytosine then guanine Will join in with And between Adhennin and Thaimin Always two headers always two bonds And in the base pairs of C and G always in the base pairs of Cytosine and Guanine Three hydrogen bonds are formed and this fixed pairing is known as complementary base pairing Because in it Adenine is always paired with Thymine and Cytosine w will pair with guanine as well and likewise If we have a DNA strand based on the weight of the substance and We don't know what's in the other strand Thus we can easily determine What the second strand will be like Because we know that T will come with A and G will come w C will come and the DNA we have has antiparallel nature The two strands we have If the first strand is progressing at a rate of 5 days to 3 days So where there was previously a 5-day Strand Then there will be a 3-day event at the second strand And wherever there was previously a 3-Day Strand The second strand will have 5 days there and this antiparallel orientation It greatly assists in DNA replication Because we have certain enzymes because DNA has The time to replicate has come just like we have DNA Polymerase This can only work in 5 days down to 3 days and between DNA strands The hydrogen bonds forming here are It stabilizes DNA Forever and we know it at between A and T Hydrogen bonds have increased The base pairs within the double helix we have Base pairs are not always spaced at a uniform distance So that's how we end up with some grooves One says we are Major Groove one says They say we're Minor Groove this Minor here Groove and Major Groove are very Become more important than anything else Because any proteins that are They bind with DNA in these minor grooves They get drawn to the Major Group So in the end if were to summarize the entire class We learned that DNA consists of two strands and these two strands are They are antiparallel the base pairing that occurs is always what What does complementary mean What will always be in between A and T is two hydrogen bonds And C is always paired with G with exactly three hydrogen bonds always present between them And whatever we have—Sugar and Phosphate —will be celebrated as the backbone The bases are inside They will be connected to each other and this one— Double Helix has turns in it always and every turn What lies between 10 base pairs are and what is their length 3.4 nanometers And the very structure of this Dedede's desig He can replicate it so perfectly And so much within oneself Genetic material degrades over time That very essence is our Molecular Blueprint So up to now I've been in the video Why teach anything at all if it lacks If anything about it has made sense to you So you can subscribe to my
