Gut-1 RNA motif
Encyclopedia
The Gut-1 RNA motif is a conserved RNA
structure identified by bioinformatics
. These RNAs are present in environmental sequences
, and as of 2010 are not known to be present in any species
that has been grown under laboratory conditions. Gut-1 RNA is exclusively found in DNA
from uncultivated bacteria
present in samples from the human

RNAs present in environmental samples
A wide variety of non-coding RNAs have been identified in various species of organisms known to science. However, RNAs have also been identified in "metagenomics" sequences derived from samples of DNA or RNA extracted from the environment, which contain unknown species. Initial work in this area...

Species
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

DNA
Deoxyribonucleic acid is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms . The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in...

Gut (zoology)
In zoology, the gut, also known as the alimentary canal or alimentary tract, is a tube by which bilaterian animals transfer food to the digestion organs. In large bilaterians the gut generally also has an exit, the anus, by which the animal disposes of solid wastes...
