DNA plays a fundamental role in transmitting genetic information by serving as the hereditary material that carries instructions for the development, functioning, and reproduction of living organisms. Its sequence of nucleotide bases (adenine, thymine, cytosine, and guanine) encodes genetic information, which determines the sequence of amino acids in proteins, thereby influencing an organism's traits. Due to the complementary base-pairing and double helix structure, DNA can replicate faithfully during cell division, ensuring that genetic information is accurately passed from parent cells to daughter cells and from parents to offspring. This replication and transmission mechanism enables organisms to inherit traits and maintain biological continuity across generations
