One apparent association, the preponderance of RUP elements and IS elements adjacent to pseudogenes, seems likely to reflect the tolerance of repeat insertions into regions of the genome that are no longer functional.
Nonetheless, they clearly indicate that the preponderance of P elements in proximal promoter regions of heat-shock genes is not universal in the genus Drosophila.
Among the inserted repetitive DNA sequences, a remarkable preponderance of mobile elements, satellite DNAs, microsatellites and multigene families, which can remodel euchromatic structures into heterochromatin, has been observed [ 17, 22- 25].
This reveals a preponderance of 5′ truncated elements consistent with what is known about L1 insertions, however, few elements contain 3′ truncations [ 57].
This coincides with direct confirmation of the preponderance of long interspersed elements in mammalian genomes at the nucleotide level by large scale sequencing efforts.
We observed preponderance of flanking repetitive elements (REs), albeit partial copies, especially of the RTE-like and Perere class at either side of the duplication source locus.
Proclus admits that the heaven is composed out of the four elements with a preponderance of fire, but he insists that the elements are not present in the celestial bodies in the same mode as they exist in the sublunary bodies.
This may partially reflect the presence of CpG islands in gene promoters as well as the preponderance of G-C rich repetitive elements such as Alu sequences that are coincident with coding regions of the genome.
The result is that a few borderline elements lacking a preponderance of either nonmetallic or metallic properties are classified as metalloids; and some elements classified as nonmetals are instead sometimes classified as metalloids, or vice versa.
Despite the preponderance of inactivating mutations, phylogenetic studies suggest that HERV elements continue to undergo extensive inter-element recombination [ 22].
