The -1,4 glycosidic linkage is present in both plants and animals.In plants, starch contains this linkage and in animal cells glycogen consists of glusose units linked by -1,4 glycosidic linkage. Both starch and glycogen are important storage polysaccharides in plants and animals which are basically glucose polymers.
The -1,4 glycosidic linkage is present in plants and fungi, arthropods. In plants, cellulose which is the primary component of plant cell wall contains repeating units of glucose linked by -1,4 glycosidic bonds. Chitin which is also the primary component of fungal cell wall and the exoskeleton component of arthropods consists of -1,4 glycosidic linkages.
b) Nucleic acid contains phosphodiester linkages between the 3'-OH group of one nucleotide and 5'- phosphate of the incoming nucleotide.
c) Carbohydrate contains glycosidic bond which may be a O-glycosidic bond or N-glycosidic bond.

DNA is the molecule used to store the genetic code of most living organisms on earth. Its structure was famously proposed by Watson and Crick who proposed double helix structure published in the journal Nature, April 25, 1953. For this the Nobel Prize was awarded to Watson, Crick & Wilkins in 1962. (a) (i) (ii) Show the chemical structure of the DNA backbone.
