List three functions of nucleotides in a cell.

Explanation

### Step-by-Step Solution

1. **Understanding Nucleotides**: Nucleotides are organic compounds that consist of a nucleoside (which is made up of a nitrogenous base and a sugar) and one or more phosphate groups. They are fundamental components of nucleic acids.

2. **Function 1 - Building Blocks of Nucleic Acids**: One of the primary functions of nucleotides is that they serve as the building blocks for nucleic acids, such as DNA and RNA. These nucleic acids are essential for storing and transmitting genetic information.

3. **Function 2 - Energy Carriers**: Nucleotides also function as energy carriers in the cell. A well-known example is adenosine triphosphate (ATP), which is often referred to as the energy currency of the cell. ATP provides the energy required for various cellular processes.
