Question : Read the following statements and choose the correct option. (a) Nitrogenous base is linked to the pentose sugar through a N-glycosidiclinkage. (b) phosphate group is linked to 5^' -OH of a nucleoside through phosphester linkage. [c) Two nucleoside are linked through 3^'-5^' N-glycosidic linkage. (d) Negatively charged DNA is wrapped around positively charged histone octamer to form nucleosome. (e) The chromatin that is more densely packed and stains dark is called euchromatin.

Answer»
