DNA or deoxyribonucleic acid is a long molecule that contains our unique genetic code. Like a recipe book it holds the instructions for making all the proteins in our bodies. DNA replication is the process by which DNA makes a copy of itself during cell division.
Human DNA contains 23 pairs of chromosomes, made up of hydrogen, nitrogen, oxygen, carbon, and their acidic counterparts. Encoded within these elements is an amazing blueprint of life that proves the Creator has put His own unique stamp upon every person.
