retrotransposon

[¦re·trō·tranz′pō‚zän]
(cell and molecular biology)
A small, mobile deoxyribonucleic acid (DNA) sequence that can retrotranspose, that is, move from one genomic location to another by producing ribonucleic acid (RNA) that is transcribed by reverse transcriptase back into DNA which is then inserted at a new site.

Both genetic and epigenetic variation in DNA methylation reprogramming genes and in LINE1 retrotransposons may play important roles in downstream cardiovascular consequences of prenatal air pollution exposure.
Having this retrotransposition ability, retrotransposons can induce massive chromosomal rearrangements thus influence an increase, change and functionality of genome shape which have been documented extensively in different type of plant species (Grandbastien, 2015).

Thus, it is highly probable that the LTR retrotransposons served as one of the driving forces in mammalian evolution; the acquisition of novel genes from LTR retrotransposons is one of the important evolutionary mechanisms as well as being a gene/ gemome duplicating mechanism.
