Whats the difference between chromosomes, DNA and a gene?
Your body is made up of trillions of cells. In each cell there are normally 46 chromosomes. We get 23 chromosomes from our mother and 23 chromosomes from our father. Thus, our chromosomes come in pairs. The chromosomes are made up of DNA. The DNA or deoxyribonucleic acid is a chemical code or instructions that direct how your body is developed. Each chromosome has very specific chapters that tell the cell what kinds of characteristics you will have (like eye color and hair color). Each of these chapters that code for a specific trait is called a gene. Genes are small pieces of DNA that have information about your traits. How come sometimes you inherit certain traits from your parents and sometimes you don’t? Genes, like the chromosomes, come in pairs. Each person receives one copy of a gene from their mother and one from their father. Even though you get half of your genes from your mother and half from your father, sometimes one gene is dominant over the other gene. An example would b
