Why do mitochondria have their own DNA?

Mitochondria are in cold blooded animals too.

There is the outline of a hypothesis here: http://www.ruf.rice.edu/~bioslabs/studies/mitochondria/mitorigin.html

All your examples of symbiosis came after the assumed mitochondria merger, not before. All your examples also allow both organisms to retain their integrity and autonomy. The bacteria that live in our gut have retained the genes that allow these to be autonomous. These bacteria have not lost most of their DNA, with the human gut doing that work form them.

The mitochondria have lost much of its DNA, with the cell needed to provide for the mitochondria. This is not the same as living in harmonious symbiosis. It is more like slavery, where the mitochondria became shackled, forced to work in the energy mines. Its legs have been broken so it can't function on its own, and leave like it came in. Its original autonomy has been gutted. This is not symbiosis.

The question of this topic is why do the mitochondria still have DNA? As an extrapolation of accepted theory, original cell and mitochondria, before the merger, would have been originally autonomous. The mitochondria will then enter the cell with hope of finding a friends that can share the work, in symbiosis. However, what it finds is a slave owner cell, who is lazy and need the modern mitochondria as a slave, since the host cell has lost its ability to take care of its own energy needs? To keep him working, did it need to shackle the mitochondria and even cuts off its legs, so it can't leave? The final mitochondria work force has two strong arms, but no legs, so it can work, but it can never leave; Hotel California.

Does this have mass appeal or is it easier to say these are not intelligent things with an agenda. Rather this the merger was all based on chemical equilibrium and not personification scenarios for those who reason with emotions induced by chance.

Does anyone have lab proof that some chance meeting and symbiosis is how the mitochondria and cell merged, or is this consensus science based on prestige; subjectivity? The consensus, has hundred in not thousands of labs, so I assume at least one of which should have done this in the lab by now.

My prediction is no proof will be offered, because none exists. We will just see insults to protect pseudo-science traditions, based on casino math and active imagination. There is no chemical logic offered. That is taboo.

2 points here:
First you state that much of the DNA has been lost in mitochodria indicating that you agree that it at one time was an autonomous bacteria with intact DNA. I guess the other option is that God decided to give some of the organelles DNA (that rascal!).
Secondly of course this symbiosis.

Mean old nature!

It is not easier to say they aren't intelligent things with an agenda; it would be irresponsible to say they are intelligent things with an agenda.

All the evidence (which you seem to be ignoring) that has been given to you is from the lab.

I guess if you ignore the evidence then you will not see any.

 

So what benefit you think mitochondria provides to the host cell. mitocondria also have a production of lysosomes which is a part of defence mechanism in case a malfunction takes part in the host cell.

 

I don't know if in case of a sperm there is an symbiotic effect were the sperm propels the head but does not penetrate into the ovom , but I don't know if the flagellum is a sack with mitochondrial inside .

 

They are the primary source of ATP.
