Structurally defined, a genome is an organization of genetic information consisting of nucleic acids (deoxyribonucleic acid or ribonucleic acid). All the activities of an organism are controlled by genes. Although not limited to the following, some general topics include: genomes. Genetic engineering, also called genetic modification, is the direct manipulation of an organism’s genome using biotechnology.
