Answer 2

Deoxyribose+phosphate group+cytosine is a nucleotide found in DNA. (option 4)

• A nucleotide is the monomeric unit of a DNA strand which is made up of three important components- deoxyribose sugar, phosphate group and nucleotide base.
• A deoxyribose is a pentose sugar in which the hydroxyl group attached to the 2' carbon atom has lost its oxygen atom.
• A phosphate group is attached to the 5' carbon of the sugar. This structure is a monophoshpate.
• A nucleotide base (eg: cytosine) is attached to the 1' carbon of the sugar. This in-turn bonds with the purine (eg: guanine) of another nucleotide.
