ADN, or deoxyribonucleic acid or DNA in english, is the inherited material in humans and in almost all other organisms. Almost every cell in a person’s body has the same ADN.

Most ADN is found in the cell nucleus (where it is called nuclear ADN), but a small amount of ADN can also be found in the mitochondria (where it is called mitochondrial ADN), but this is not all that ADN means.

Your ADN is what makes you unique. It’s that double helix your genes are made of. ADN stands for deoxyribonucleic acid, sometimes called ” the molecule of life, ” since almost all organisms have their genetic material encoded as ADN.

 Since each person’s ADN is unique, “ADN typing” is a valuable tool for connecting suspects to crime scenes.

Information in ADN is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human ADN consists of approximately 3 billion bases, and more than 99 percent of those bases are the same in all people.

The Order of ADN

The order or sequence of these bases determines the information available to build and maintain an organism, similar to the way the letters of the alphabet appear in a certain order to form words and sentences.

The ADN bases pair with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called nucleotides.

You already know it’s ADN.
