DNA: Storage of Genetic Information

DNA contains the instructions required for cellular activities and the inheritance of biological characteristics. In eukaryotic cells, most DNA is located in the nucleus, while additional DNA is present in mitochondria.

DNA contains genes, which are functional sequences that contribute to the production of RNA molecules or proteins. Before cell division, DNA replication allows genetic information to be transmitted to daughter cells.

DNA analysis is widely used in genetic research, molecular diagnostics, biotechnology, genome sequencing, and the study of biological diversity.
