What inside our bodies makes us grow in a certain way? The answer is DNA. It was first discovered by a young Swiss doctor in 1868. DNA is like a computer program for your body. Almost every cell in your body includes DNA. The way DNA in the cell decides why you are the way you are. For example your friend might have larger ears than you. This is because their DNA is different from yours. DNA lives in the cell and is ordered in a structure called a "double helix ". In each double helix there are links called as chromosomes . These chromosomes are made from four bases that arrange themselves in millions of different ways. The way these bases choose to line up is what makes the DNA code for that cell. DNA is also called a "gene ". This is a very interesting thing. Genes are passed down from your parents. That is why you might have the same smile like your dad's or mom's!
