Eukaryote organelles - DNA?

Post by JeanTate » Wed Jul 21, 2010 7:21 pm

Which non-nuclear organelles are known to contain their own DNA? And which of these are thought to have a common ancestor?

As far as I know, mitochondria, all mitochondria in all (non-extinct) eukaryotes, contain DNA, and it is thought to have a common ancestor.

Plants contain plastids (as well as mitochondria), which all contain DNA (right?). However, collectively, the plastids' DNA does not have a common ancestor, right?
