(Taenia solium, Taenia saginata, Taenia asiatica) and associated diseases. Life cycles of all taenids are very similar. T. solium is distinguished by its ability to use humans not only as definitive hosts but also as intermediate hosts. Because of this, the species is most important within this group of parasites.Taenia solium, Taenia saginata, Taenia asiatica) and associated diseases. Life cycles of all taenids are very similar.

Definition of a Transcription Factor. Genes contain all the information a cell needs to carry out daily processes and are comprised of DNA. Since genes cannot leave the nucleus, they must be copied through a process called transcription. The copy, called mRNA, is then turned into a gene product.
