Bacterias & Prokaryotes

Archaea is considered to be an separate ambit, besides Prokaryotes (which allow in bacteria) and eukaryotes (which include plants, animals, fungi and protests). Eukaryotes have a well-defined nucleus, membrane cell structure. On the early(a) hand prokaryotes have a well-defined cell paries and contain an irregular nucleus. Archaea was defined in the 1970s, and it was observed that they survived at uplifted temperatures (above 100 degrees centigrade), pressure or salt concentrations and is known as extremophiles. They whitethorn produce methane gaseous state as part of metabolism.They were found in regions other than which other organisms lowlifefulnot survive such as geysers, oil wells, deep ocean, hypersaline waters, glowing springs, etc, and hence could be helping to maintain the ecological niche. As they can survive only in very high temperatures in which other forms of life cannot exist, they were considred to be absent in the tender body. However, scientists are consid ering that Archaea domain can in fact be hand in the human body and can ca map disease. Under a normal microscope viewed downstairs standard conditions, Archaea would appear as small dots, as they are unchanging at this room conidtions (B.Waggoner & B. R. Speers. 1994). With the help of an electron microscope can the Archaea domain can be examined. There are several other techniques of examining the Archaea species. Molecular techniques expect to be very effective in detecting and isolating Archaea as their genetic material can be identified (especially PCR). The charge of lipids present in the Archaea cell can be determined with the help of gas chromatography and mass spectroscopy. Fluorescent in situ hybridization is also utilized in some instances to study the relationship between the genetic material of Archaea and the presence of diseases.Immunological methods such as in situ immunofluorescence and immunohistochemistry are being studied as to how they could be utilized in detecting Archaea. They are of limited use as there are some issues with the antigen produced by Archaea (P. B. Eckburg. 2003 & E. F. DeLong, 1999). References B. Waggoner & B. R.
