Nucleotides are components of RNA and DNA strands that code for genetic information.
In the same way that words in a book come together in order to form a story, the information in nucleotides represent the proteins that make up your body.
Nucleotide Structure:
Each nucleotide consists of a phosphate group, a ribose or deoxyribose 5-carbon pentose sugar molecule, and a nitrogenous base.
The type of nucleotide is determined by the type of nitrogenous base that it is attached to.
Example:
The nucleotide Thymine (T) is called Thymine because its nitrogenous base is a thymine molecule.
