Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants. </span>
The manipulation of genes for practical purposes, such as medicine, agriculture, or criminal justice, is called GENETIC ENGINEERING. These technologies involve the manipulation of the DNA molecule.
Deoxyribonucleic acid (DNA) is the molecule that carries the instructions (i.e., genes) for all organisms to develop, survive, grow and reproduce.
Genetic engineering techniques consist of the manipulation of the DNA molecule in order to produce desirable phenotypic features in the offspring of an organism.
Genetic engineering techniques use recombinant DNA strategies to modify the genetic makeup (DNA) of the target organism.
