Which genetic material stores hereditary information in almost all living organisms, structured as a double helix?

💡 Solution & Explanation

Deoxyribonucleic acid is the primary hereditary material in humans and almost all other organisms, structured as a double helix composed of nucleotides containing a sugar-phosphate backbone and nitrogenous bases. Ribonucleic acid primarily functions in protein synthesis and gene expression rather than long-term genetic storage. ATP acts as the universal energy currency of cells, transferring chemical energy for metabolic processes.
