Hydrogen bond between Adenine and Thymine | Adenine Thymine base pair | nitrogenous base pairing in DNA, in DNA double helix structure proposed by Watson and Crick. two strand of DNA a joint by nitrogenous base pairing in which adenine combined with thymine with double hydrogen bond • Watson and Crick model of DNA double helix structure | डीएनए की द्विकुण्डली संरचना, • James Watson and Francis Crick in 1953 proposed the helical structure of DNA for which they were awarded with Nobel Prize in 1962. the two strand of DNA are helically coiled in such a fashion that base molecules of two strand are linked Together by weak hydrogen bond to constitute base pair. the two right handed helix coiled in interlocked form about same axis. each turn of double helix contains 10 bp nucleotide. distance between two paired nucleotide is 0.34nm (3.4A°) and distance between 1 turn is 3.4nm (34A°). adenine is always paired with thymine with double hydrogen bond and guanine paired with cytosine with 3 hydrogen bond. • #biologysir #balramsir #basepair #dnastructure #chargaff'srule #purine #pyrimidine #nucleicacid #dna #rna #genetics #nucleotide • Hi guys myself Balram Prasad Gupta (Balram sir) and you are watching Biology Sir YouTube channel, if you are enjoying the video to see on this channel, pls subscribe, like, comment and share it.
