DNA is deoxyribonucleic acid. It is the nucleic acid that performs the task of coding the genetic material which determins the makeup of all living cells. It consists of two long strands of nucleotides these link together in a structure resembling a ladder twisted into a spiral. This sort of DNA can run into many thousand or even hundreds of thousand of base pairs on each strand. The DNA that TraceTag DNA utilises is of a very short chain design and single stranded, increasing the chemical strength and is therefore more resistant to attack by Chemical removal ,UV, shear pressure and enzyme activity.
