Answer 1

Answer:

A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base.

Functions

1. Nucleotides are the basic units of nucleic acids (DNA and RNA). Though, nucleoside monophosphates found in nucleic acids, actually nucleoside triphosphates are the raw materials for their synthesis.

2. Cyclic Nucleotides Act as Regulatory Chemicals. Cyclic AMP (cAMP) functions as second messengers in many hormone actions, while cyclic GMP (cGMP) functions in Ca++ or calmodulin mediated responses.

3. Nucleotides of B-Complex Vitamins Function as Coenzymes. For example, NAD+, NADP+, FMN, FAD are coenzymes useful in oxidation-reduction reactions.
