DNA is recognized as the genetic material of the cell because it carries the instructions necessary for the growth, development, functioning, and reproduction of all living organisms and many viruses. In eukaryotic cells, DNA is organized into structures known as chromosomes, which are located within the nucleus. This molecular structure is vital because it not only stores genetic information but also plays a crucial role in the processes of replication and protein synthesis.

While RNA is involved in the transmission of genetic information and serves various functions in protein synthesis, it is not the primary genetic material in cells. Proteins are crucial for a multitude of cellular functions but do not serve as genetic material. Lipids, although important for forming cell membranes and storing energy, do not carry genetic information. Therefore, DNA is uniquely positioned as the molecule that encompasses the hereditary information required for the life processes of an organism.
