I am looking forward to the real Jurrassic Park :D

I love dinos, lol

Meh, if there was a real Jurassic Park, then it would be very difficult to control, because of yes, like Malcolm said, chaos theory. So many factors that we really don't know about. For example, just because someone has a large brain, doesn't mean he's smart; there could be nothing inside.
And any of those dinos could have something we don't know about them.
Otherwise it would be cool to see dinosaurs in real life.

I never said anything about "absorbing DNA from the host animal". Mitochondrial DNA comes from wherever the egg came from. In a non-cloned animal, that's the mother. In a cloned animal, that's the egg donor.

Most proposals I've heard for bringing back extinct animals use a related, still-living species as a surrogate mother - elephants for mammoths, for example. That'd mean the mammoth would acquire some immune protection from the elephant "mother" to get started and so probably wouldn't die horribly of assorted diseases.

Sorry, but the egg is already fertilized, once within the host animal, so the maternal DNA is already present.
Sorry if I seem obstinate, I just really don't get it. v.v

Mitochondria are the component of cells primarily responsible for production of ATP (the chemical used as an energy source in your body, converted from the nutrients you ingest), but with effects on things like cell division and cell death, as you may know. What you may not know is that they have their own DNA - they are not controlled by the DNA in the nucleus, but are effectively independent micro-organisms in a symbiotic relationship with pretty much all known forms of life (the exception being a handful of single-celled organisms like amoeba).

But even if a real mammoth "fetus" is inside the elephant, we can't control everything and there will be changes to the mammoth to not make a it genuine mammoth, and then we'll create something else.
Er...I just read the below posts. Meh, reminds me off House of Scorpion.
Though Mitochondria will make sure the mammoth will not inherit any elephant characteristics...well I still don't see it all...I just don't get how mitochondira will do that...

...what?
No DNA comes from the animal the egg's implanted in. Mitochondrial DNA comes from the egg donor and the nuclear DNA (i.e., everything but the mitochondrial DNA) comes from whatever you've cloned.

No, the mitochondrial DNA is from the maternal batch of 23 chromosomes, not the animal holding the egg.

No. It's not from the animal holding the egg OR from the mother's chromosomes. It's from the egg donor. In most cases (i.e. other than some cloning or some other artificial fertilization methods) this is the mother, but even then it's not from her chromosomes. Mitochondria has its own DNA - and it's not a chromosome. It's a circular ring of DNA (as found in bacteria) containing about 16,000 base pairs - 37 genes.

lost again.

All I know is that mDNA passes down from mother to daughter...

What were we talking about again?
:D
