Horizontal gene transfer


Horizontal gene transfer is a mechanism by which an alien gene from a source "organism X," moves into, or is taken into, a given cell and is somehow incorporated into the genetic complement of the cell.

Horizontal gene transfer from human papillomavirus 18 (HPV18) to human cervical cells created the HeLa genome which is different from either parent genome in various ways including its number of chromosomes.

Horizontal gene transfer is invoked to explain how there is often extreme similarity between small portions of the genomes of two organisms that are otherwise very distantly related. Horizontal gene transfer seems to be common among many microbes.
