What is DNA (Deoxyribonucleic acid)


DNA is like a large instruction book, approximately 800 Bibles long, written in the strange language "genish", which consists of only four letters (A,C,T,G).

This book of life contains everything needed to know about building and maintaining a living organism and it directs all the events performed by a cell.

In our cells the DNA is located in the nucleus and packed into 46 chromosomes, 23 from the mother and 23 from the father which combine to form a unique individual. How is this book of life, the DNA, inherited from one cell to its daughter cells and from one generation to another?

The answer is replication.

The information in the DNA is divided into different regions called genes, The genes are the recipies for proteins, the building blocks and workers in our bodies.
