Your DNA is what makes you uniquely you. It's that double helix that your genes are made of. Your DNA accounts for why you resemble your parents and it distinguishes you from your pet frog and from everybody else.
DNA stands for deoxyribonucleic acid, sometimes called "the molecule of life," as almost all organisms have their genetic material codified as DNA. Since each person’s DNA is unique, "DNA typing" is a valuable tool in connecting suspects to crime scenes. You can also use the word less scientifically, as in “it’s just not in my DNA to sit through six hours of meetings.”
