Cross-Regulation between Transposable Elements and Host DNA Replication

Cross-Regulation between Transposable Elements and Host DNA Replication

Transposable elements subvert host cellular functions to ensure their survival. Their interaction with the host DNA replication machinery indicates that selective pressures lead them to develop ancestral and convergent evolutionary adaptations aimed at conserved features of this fundamental process. These interactions can shape the co-evolution of the transposons and their hosts.

Transposable elements and host genome evolution.

Several recent reports have challenged the idea that transposable elements (TEs) are mainly 'selfish' or 'junk' DNA with little importance for host evolution. It has been proposed that TEs have the potential to provide host genomes with the ability to enhance their own evolution. They might also be a major source of genetic diversity, allowing response to environmental changes. Because the rela...

Perspective : Transposable Elements , Parasitic Dna , and Genome

The nature of the role played by mobile elements in host genome evolution is reassessed considering numerous recent developments in many areas of biology. It is argued that easy popular appellations such as ‘‘selfish DNA’’ and ‘‘junk DNA’’ may be either inaccurate or misleading and that a more enlightened view of the transposable element-host relationship encompasses a continuum from extreme pa...

Transposable Elements: No More 'Junk DNA'

Since the advent of whole-genome sequencing, transposable elements (TEs), just thought to be 'junk' DNA, have been noticed because of their numerous copies in various eukaryotic genomes. Many studies about TEs have been conducted to discover their functions in their host genomes. Based on the results of those studies, it has been generally accepted that they have a function to cause genomic and...
