The Role of DNA in Heredity

In the fascinating world of genetics, DNA plays a crucial role in heredity. DNA, or deoxyribonucleic acid, carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms. It is responsible for passing on traits from parents to offspring through the process of reproduction. In humans, DNA is composed of two long chains that coil around each other to form a double helix, containing the genetic information that determines an individual's unique characteristics. Understanding the role of DNA in heredity is fundamental to comprehending the inheritance of traits and the complexities of genetic variation.
