This podcast explains how genes, molecules, and cells work together in the creation of a human being. The sperm and the egg join and the parents' genes combine to determine the baby's physical characteristics. The first cell that forms is the fertilised egg and it forms the first copy of the DNA molecule which carries the code in every cell of the person's body. DNA is a molecule of considerable size and contains the genes which determine the colour of the eyes and hair, height, facial features, skeletal shape and other details. The coordination of this complex structuring is brought about by the DNA molecule, which contains enough information to fill a million encyclopaedia pages. This is a miracle of design and creation within our bodies, and the Qur'an pointed to the concept of "genetic planning" in an age when knowledge was limited.
