Deoxyribonucleic Acid (DNA)
Definition - What does Deoxyribonucleic Acid (DNA) mean?
Deoxyribonucleic acid (DNA) is the unique genetic code of every individual organism. All organic life forms are comprised of DNA coding, which, when translated by science, is a map of a person's individual genetic makeup.
Some DNA is passed on from our parents and grandparents, giving an entire and complete genetic history.

In horticulture, plants have this same genetic mapping. DNA technology has more accurately been able to classify a genus, an individual species, and an individual plant by its DNA coding.
Cloning is a process where a complete and accurate DNA duplicate may be reproduced exactly as the parent. Plants are unique in the respect that cloning is not a complicated scientific process and in fact occurs naturally much of the time.
Plants can be cloned using stem cuttings or naturally by a branch or stem bending to the ground and taking root. The plant produced through this method is an exact genetic copy of the parent or host plant.
Plants such as bridlewreath spirea or of the corral berry family reproduce mainly by cloning themselves. In every case, the offspring will be an exact DNA copy of the parent plant.
The same is true in the greenhouse where perennials or shrubs are reproduced using stem cuttings. This means that there may be thousands of individual plants out there with exactly the same deoxyribonucleic acid or DNA code.
