An article published in the journal “Genome Biology” describes a research on some transposons, commonly called jumping genes because they can move within the DNA of an organism, typically leaving copies of themselves in the original location. A team of researchers looked for traces of two transposons, identified as L1 and BovB, in 759 species of plants, animals and fungi. Their theory is that they have become parts of mammalian DNA through a horizontal gene transfer, which means acquiring them from another species.
