Naw, that's just the fact mitochondria are the reason life is as we know it. It's pretty much the cousin of chloroplast too!

But mitochondria actually forfeited a majority of its genome to the host organism when it became the powerhouse of the cell. This is how we influence it's processes and output. It did retain enough of it's genome to be able to synthesize the required proteins for the job, but all in all, the host is in control of the mitochondria.
