Question

Mitochondria are thought to be the descendants of certain alpha proteobacteria. They are, however, no longer able to lead independent lives because most genes originally present on their chromosome have moved to the nuclear genome. Which phenomenon accounts for the movement of these genes?

Answer 1

Answer:

Horizontal Gene transfer

Explanation:

The phenomenon that accounts for the movement of these genes is Horizontal Gene transfer. Also known as Lateral gene transfer is the movement of genetic material between unicellular organism other than by vertical transmission of DNA from parent to offspring. Horizontal gene transfer(HGT) is very important for the evolution of organism.
