It is very interesting to know that our body is made up of various acids. Each cell in our body contains acids. Can you think of an acid which is present in every cell and controls our looks, the colour of our eyes, our height and so on?
Deoxyribonucleic acid (DNA)
Each cell in our body contains deoxyribonucleic acid (DNA). DNA contains the genetic code that allows living organisms to create new members of their species. It controls every feature of our body, for instance, looks, height and so on. DNA passed from one human to another helps in determing gender and physical characteristics. This nucleic acid is necessary for the survival of species.
