DNA is the backbone of inheritance. It is DNA and RNA that carry all information possible into an organism since its conception, even before its birth. How to walk, breathe, grow, and exist is all programmed into an organism by its DNA. An explanation would be thus: the DNA of an organism contains several genes, each coding for a particular compound in the body, like an enzyme, hormone, metabolite, or structural protein, all of which affect how the body functions. This DNA is given to every organism by its parent(s), given to them by their parents. In our DNA, we carry millennia of history—e familyrelics of ancestors long gone. I knew my legs were slightly bow-shaped because so are m aunt’s, and her aunt’s. I knew it runs in the family. But it was in classes eleventh and twelfth, learnedI learnt what ‘running in the family’ actualy meant, and understood the mechanism behind it. I always loved the concepts of evolution and heredity, and genetics concretizationtisation of these concepts. Within genetics, learning about the existence of pedigre charts, and the simplicity of their funtioning, remains a highlight.
