Verified step by step guidance

Understand the role of macromolecules in biological systems. Proteins, lipids, polysaccharides, and nucleic acids (like DNA) each have distinct functions.

Recall that genetic information is stored in the form of sequences of nucleotides, which are the building blocks of nucleic acids such as DNA and RNA.

DNA (Deoxyribonucleic Acid) is the primary macromolecule responsible for storing genetic information in most organisms. It contains instructions for protein synthesis and cellular functions.

Proteins, while essential for cellular structure and function, do not store genetic information. They are synthesized based on the instructions encoded in DNA.

Lipids and polysaccharides primarily serve roles in energy storage, structural integrity, and signaling, but they do not store genetic information.
