What complex molecule contains genetic information?

• A. RNA
• B. DNA
• C. Protein
• D. Carbohydrate

Answer: (B)

The complex molecule that contains genetic information is DNA. Deoxyribonucleic acid, or DNA, is the hereditary material found in all known living organisms and many viruses. Its structure consists of two long strands forming a double helix, with each strand made up of sequences of nucleotides. Each nucleotide contains a phosphate group, a sugar, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). The specific sequence of these bases encodes genetic information, determining the traits and functions of an organism. DNA serves as the blueprint for all biological systems by carrying the instructions needed for the growth, development, functioning, and reproduction of organisms. This genetic information is passed from generation to generation through processes such as DNA replication and transcription, ultimately leading to the synthesis of proteins through translation. In essence, without DNA, the molecular basis of heredity and the biological diversity we observe would not exist. While RNA also plays a crucial role in the expression of genetic information, serving as a messenger and executor in protein synthesis, it is DNA that primarily contains and stores the genetic blueprint in a stable form. Proteins and carbohydrates, while vital for cellular structure and function, do not carry genetic information directly like
