Retrotransposons can act as molecular markers because they have conserved sequences and their replication leads to polymorphism in genomes.

Retrotransposons -- DNA sequences able to replicate and move to other places -- make up a substantial fraction of the human genome.
Class I TE known as retrotransposons were found abundantly in both QTLs, with a composition of 42 genes in qBFR4 and 78 genes in qLBL5.
In the genus Festuca, for example, it was reported that the proliferation of GC-rich retrotransposons in the genome of basal species with the subsequent reduction of the C-value and GC content was related to the evolution of this genus (Smarda et al.
An ancestor to retroviruses, called retrotransposons, inserted its genetic material into the animals' DNA.
Repetitive DNA--specifically, transposable elements (TEs)--constitutes at least 45% of the human genome, wherein the fraction of long interspersed nucleotide element (LINE) retrotransposons is 17% [1].
Happle later proposed the theory that transposable elements or retrotransposons within the human genome, which affect the activation or silencing of genes, could cause linear skin lesions following BL.
Approximately 40% of the mammalian genome is comprised of retrotransposons, implying their important role in organizing genomic architecture, orchestrating biological processes, and contributing to species diversity and evolution.
One of the principal alterations is the DNA demethylation with defective satellites and retrotransposons, splicing mutations, polymorphisms, and miRNA overexpression [26].
Retrotransposons are transposable elements (TE) that generate new copies via an RNA intermediate.
