"Pheromones are chemicals emitted by living organisms to send messages to individuals of the same species. The class most widely explored are the sex pheromones produced by female moths which are used to attract conspecific males for mating. Bombykol, the sex pheromone of the silkmoth, was first synthesized in 1959." The above is from a cornell website about pheromones. Pheromones are thought to bind to receptors which are found in a structure in the mammalian nose known as the vomeronasal organ (VNO). Binding of chemicals to receptors leads to a series of signalling events none of which include changing DNA. Thus it is very unlikely that pheromones change DNA, although they may lead to increased transcription of genes which are coded by DNA. hope this helps, gabriel vargas md/phd References http://www.nysaes .cornell.edu/pheronet/pherom.html http://web.sfn.org/content/Publications/BrainBriefings/pheromones.html a>
