(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.

It can also be visualized by electron microscopy.ranscription unit. Definition. noun. A stretch of DNA being transcribed into an RNA molecule. Supplement.

Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.
