DNA, or deoxyribonucleic acid, carries genetic information in our cells. DNA is found in all living things, from plants to humans! DNA gives cells the information to make different proteins, which help the animal survive. The DNA is contained inside of chromosomes, which are like sorting boxes. Inside of the DNA are specific genes that determine a characteristic. The genes define one trait and the DNA is made out of many genes. DNA is made out of base pairs, which are the fundamental building blocks of genetic code. They are adenine (A), thymine (T), guanine (G), and cytosine (C). Adenine always pairs with thymine (A-T) and guanine with cytosine (G-C). This forms the genetic code and the “rungs” of the “DNA ladder”.
