What is the function of DNA in living organisms?

DNA plays a crucial role in living organisms by serving as the molecular blueprint for life. Its primary function is to store and transmit genetic information, which is essential for the development, functioning, and reproduction of all living things. Each gene within the DNA encodes specific instructions for synthesizing proteins, which are vital for carrying out various cellular functions and processes.

The structure of DNA, consisting of two intertwined strands forming a double helix, allows it to replicate accurately during cell division. This replication is necessary for passing genetic material from one generation to the next, ensuring continuity of biological traits. When cells need to produce proteins, the DNA sequence is transcribed into messenger RNA, which then translates this information into amino acid sequences, ultimately forming proteins.

While other options may describe processes important for life, they do not capture the essential role that DNA plays in genetic information storage and transmission, which is foundational for all aspects of biological inheritance and diversity.
