Some of the known core promoter elements are the TATA box, the first element identified in eukaryotic genes, the initiator element and the downstream promoter element [ 11].
Previous studies, which were based on fewer than 25 BEL/Pao elements, identified five superfamilies of BEL/Pao elements: Pao, Sinbad, BEL, Tas and Suzu [ 16, 23], named after the first element identified in each superfamily.
The first element identified was the Lats kinase, (Xu et al, 1995) and evidence for a pathway was provided by the elucidation of Salvador (Tapon et al, 2002), which encodes a non-catalytic protein that binds directly to Lats and has a similar LOF phenotype.
This argument has several elements.[21] The first element identifies an individual's well-being with her preferences.
It is the second repressor element identified at the SCL locus - the first being found in the 3' UTR of the SCL gene [12].
PEVE is the first viral element identified in free-living flatworms.
PEVE is the first viral element identified in planaria, and comprises two potential helicases that are homologous to proteins from distant viral phyla.
The second element of luck that Prusiner identified is that "another scientist could have discovered" the existence of prions, but no one else did.
The second element is authenticity.
The man who raised the stone is named with the runes þru ikr and the name was identified as Þrýríkr by Sophus Bugge who identified the first element of the name as the noun þrýð- that would be derived from a *þrūði- and correspond to Old English þrýðu ("power", "force").
Among the LTR retrotransposons, the gypsy-type ranked first, which was the only LTR element identified by RepeatMasker using the A. gambiae repeat database.
