DNA = deoxyribonucleic acid [de ox ee rye bo new clay ic • ass id]
A long chemical molecule that contains the genetic material in the cell. DNA is made up of four building blocks or bases, known as adenine (A), thymine (T), cytosine (C) and guanine (G). These bases can be thought of as letters in an alphabet that spell out the instructions for making proteins. The sequence of the bases that make up the DNA is the genetic code. It contains the information, or blueprint, for making an organism (see also, gene). DNA is found primarily in the cell nucleus and is copied before cell division so that each ”daughter' cell has a complete set of genetic instructions.
Chemical changes in DNA that result from damage; occurs when chemicals attach to segments of DNA helix.
