This is substance produced by plants or animals, or a synthetic analogue thereof, that evokes a behavioral response in individuals of the producing species or other species (e.g. allomones, kairomones, pheromones, and synomones).

GMO - Genetically modified organism (GMO) is Genetic material of an organism is  altered with the help of genetic engineering techniques generally known as recombinant DNA technology. DNA molecules from one source is combined with the DNA of other in vitro into one molecule to create a new gene. The recombinant DNA is then transferred into an organism causing the expression of modified or novel traits. The product is also known as an Genetically Engineered Organism or GEO.

Examples Transgenic animals (mice, fish),  transgenic plants (BT Cotton, Flavour Savour Tomato), or various microbes (fungi and bacteria) . The production and use of GMOs are ivolved in biology or medicine, for the production of pharmaceuticals and industrial enzymes, and for direct, and often controversial, applications aimed at improving human health (e.g., gene therapy) or agriculture (e.g., golden rice). For example, a gene from a jellyfish, encoding a fluorescent protein called GFP, can be physically linked and thus co-expressed with mammalian genes to identify the location of the protein encoded by the GFP-tagged gene in the mammalian cell. The indispensable use of GMO is in many areas of research, such as to study the mechanisms of human and other diseases .

Some of the techniques used to transfer DNA  cells into animals and plants are

1) Bacterial carriers
2) Biolistics
3) Calcium phosphate precipitation
4) Electroporation
5) Gene silencing
6) Gene splicing
7) Lipofection
8) Microinjection
9)Viral carriers.

Novel feeds are feeds composed of or derived from microorganisms, plants or animal sources that:
are not approved as livestock feed in Canada (not listed in Schedule IV or V of the Feeds Regulations)
and/or contain a novel trait

Novel feeds include microbial products (e.g. forage inoculants, fermentation products) plants with novel
traits, and plants with no history of use as feed, and products/by-products of biotechnology-derived animals.

Cloned Animals

both cause harm to human health..but
bacteria is single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission; important as pathogens and for biochemical properties; taxonomy is difficult; often considered to be plants
virus is an ultramicroscopic (20 to 300 nm in diameter), metabolically inert, infectious agent that replicates only within the cells of living hosts, mainly bacteria, plants, and animals: composed of an RNA or DNA core, a protein coat, and, in more complex types, a surrounding envelope.

viruses are more dangerous than bacteria...
