(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 the genetic information stored in DNA is used to produce a complementary RNA strand. In more detail, the DNA base sequence is first copied into an RNA molecule, called premessenger RNA, by messenger RNA (mRNA) polymerase.he formation of new protein molecules is made from amino acid building blocks based on information encoded in DNA/RNA. The amino acid sequence of each protein determines its conformation and properties (e.g. ability to interact with other molecules, enzymatic activity etc).
