Conversely, there are two ITSs in eukaryotes: ITS1 is located between 18S and 5.8S rRNA genes, while ITS2 is between 5.8S and 28S (in opisthokonts, or 25S in plants) rRNA genes. ITS1 corresponds to the ITS in bacteria and archaea, while ITS2 originated as an insertion that interrupted the ancestral 23S rRNA gene. [1] [2]
The 5.8S rRNA is initially transcribed along with the 18S and 28S rRNA in the 45S preribosomal RNA, along with the ITS 1 and ITS 2 (Internal transcribed spacer) and a 5’ and 3’ ETS (External transcribed spacer). [8] The 5.8S rRNA is located between the two ITS regions, with ITS1 separating it from the 18S rRNA in the 5' direction, and ITS2 ...
The genomic sequence of the 18S rRNA is organized in a group with the 28S and 5.8S rRNA, separated and flanked by the ITS-1, ITS-2 and ETS spacer regions. [4] These regions of ribosomal DNA (rDNA) are present with several hundred copies in the active genome, clustered in nucleolus organizer regions (NORs) . [ 2 ]
Identical LTR sequences at either end of a retrotransposon. A long terminal repeat (LTR) is a pair of identical sequences of DNA, several hundred base pairs long, which occur in eukaryotic genomes on either end of a series of genes or pseudogenes that form a retrotransposon or an endogenous retrovirus or a retroviral provirus.
The receptor is located in the alimentary tract, urinary bladder, heart and adrenal gland as well as the central nervous system (CNS). [8] In the CNS the receptor appears in the putamen, caudate nucleus, nucleus accumbens, globus pallidus, and substantia nigra, and to a lesser extent in the neocortex, raphe, pontine nuclei, and some areas of the thalamus.

[1] Information systems technician is a U.S. Navy and Coast Guard specific job, also known as an enlisted rating (often called MOS by other armed services). The other U.S. Armed Forces have similar positions, but with different titles utilized (information technology specialist in the U.S. Army, data network specialist in the U.S. Marine Corps)
The Integra Type R is equipped with a 1.8-liter DOHC VTEC in-line 4-cylinder (B18C) engine. In the JDM Type R this engine produces 200 PS (197 hp; 147 kW) at 8,000 rpm, whereas in the US models it produces 195 hp (198 PS; 145 kW) at 8,000 rpm and 130 lb⋅ft (176 N⋅m) of torque at 5,700 rpm.
