71R2 RNA element — R2 RNA is a cis acting element identified in R2 retrotransposons which is involved in priming the reverse transcription process (an essential part of retrotransposon insertion into the host genome).R2 is a non long terminal repeat (non LTR)… …
72Tombusvirus internal replication element (IRE) — In virology, the tombusvirus internal replication element (IRE) is a segment of RNA located within the region coding for p92 polymerase. This element is essential for viral replication; specifically, it is thought to be required at an early stage …
73TPP riboswitch (THI element) — In molecular biology, the THI element is a highly conserved RNA secondary structure. It serves as a riboswitch [cite journal | last = Winkler | first = W | coauthors = Nahvi A, Breaker RR | year = 2002 | title = Thiamine derivatives bind… …

75trace element — n. 1. a chemical element, as iron, copper, zinc, etc., essential in plant and animal nutrition, but only in minute quantities 2. any element present in minute quantities in an organism, soil, water, etc …
76Bicoid 3'-UTR regulatory element — The bicoid 3 UTR regulatory element is an RNA regulatory element of gene expression, consisting of four domains (denoted as II, III, IV and V). It is essential for the correct transport and localisation of bicoid mRNA during oocyte and embryo… …
77Hairy RNA localisation element (HLE) — The hairy localisation element (HLE) is an RNA element found in the 3 UTR of the hairy gene. HLE contains two stem loops. HLE is essential for the mediation of apical localisation and the two stem loop structures act to allow the recognition of… …
78Hepatitis C virus 3'X element — The Hepatitis C virus 3 X element is an RNA element which contains three stem loop structures that are essential for replication. References* [1] cite journal | last = Lee | first = H | coauthors = Shin H, Wimmer E, Paul AV | year = 2004 | title …
79Hsp90 cis-regulatory element — The Hsp90 cis regulatory element is an RNA element found in the 5 UTR of the Drosophila hsp90 mRNA that is required for increased translational efficiency during the heat shock response. The hsp90 gene product is involved in the Drosophila heat… …
80Human rhinovirus internal cis-acting regulatory element (CRE) — isa CRE from the human rhinoviruses. The CRE is located within the genome segment encoding the capsid proteins so is found in a protein coding region. The element is essential for efficient viral replication and it has been suggested that the CRE …
