What do nucleic acids primarily store?

Nucleic acids, which include DNA and RNA, primarily serve the function of storing hereditary information. DNA carries the genetic blueprint necessary for the development, functioning, growth, and reproduction of all living organisms. It encodes the instructions for building proteins and passing traits from one generation to the next through the process of replication and transcription.

RNA plays a crucial role in translating this genetic information into proteins, which are vital for a multitude of cellular functions. Thus, the main role of nucleic acids is to act as the repository of genetic information that informs biological processes and influences traits across generations. This function is foundational to the understanding of genetics and cell biology, underscoring the significance of nucleic acids in life sciences.
