Biology CLEP Prep Practice Exam

What is the primary role of DNA in a cell?

1. Store energy

2. Produce proteins

3. Create copies of itself

4. Provide structure

The correct answer is: Produce proteins

DNA primarily serves as the blueprint for producing proteins within a cell. This process, known as gene expression, involves the transcription of DNA into RNA, which is then translated into proteins. Options A, C, and D are incorrect as DNA does not have a direct role in storing energy, creating copies of itself, or providing structure. While DNA does play a role in cell division and provides stability to the overall structure of a cell, these are not its primary functions.
