Step-by-step solution

Primary metabolites are found in animal tissues. While primary metabolites have identifiable functions and play known roles in normal physiological processes, the role or functions of secondary metabolites is unknown. Some secondary metabolites have ecological importance .When nitrogenous bases attached to a sugar, they are nucleosides. If a phosphate group is also found esterified to the sugar they are called nucleotides. Nucleic acids like DNA and RNA consist of nucleotides only
