Alu repeats, which belong to SINE (short interspersed nucleotide elements) family of repetitive sequences, are present exclusively in the primate genomes.
An additional element of complexity typical of repetitive elements such as VNTRs is that they are polymorphic.
The inherited active elements can produce new families of repetitive elements primarily due to fixation by genetic drift in small subpopulations.
Transposable elements are segments of repetitive DNA that can mobilize and propagate within host genomes.
Interestingly, the proportion of L1 elements that belong to older classes of repetitive elements is elevated at imprinted loci.
Therefore, hygienic behavior is not the only factor influencing the accumulation of repetitive elements in genomes.
The most abundant of repetitive elements were transposable elements (TEs) or potential TEs.
The 3D finite element (FE) models of repetitive sections of the whole TS were developed in this study.
c Number of repetitive elements nesting a given element.
The Alu element is a member of the SINE family of repetitive elements.
