The DNA molecules are useful for specifying a gene product in cells, either as a promoter or as a protein coding sequence or as an UTR or as a 3' termination sequence
, and are also useful in controlling the behavior of a gene in the chromosome, in controlling the expression of a gene or as tools for genetic mapping, recognizing or isolating identical or related DNA fragments, or identification of a particular individual organism, or for clustering of a group of organisms with a common trait.
The oxidative degradation pathway for organic polymers typically follows an initiation, propagation, and termination sequence
. The initiation, in this case the ionizing radiation, is followed by the propagation steps with atmospheric oxygen.
