Tell the bond (X, Y, Z) in the structure of DNA:
X is the bond between the two nitrogenous bases. This is hydrogen bond.There is double bond between A and T, triple bond between G and C. Y is the bond between nitrogenous base and sugar. This is beta-N glycosidic bond, which is a covalent bond. This bond is between C1 of sugar and N9 of purines and N1 of pyrimidines. Z is the bond between sugar and phosphate. This is 3' 5' phosphodiester bond.
