TL;DR
How many proteins of humans body were translated from the Mitchondria's dna?
The mitochondria has DNA code which being translated to protein in a certain amount. So how many proteins are from the mitochondria compared to the nuclues?

There are 37 genes in human mitochondrial DNA across ~16500 base pairs, which code for 13 proteins necessary for oxidative phosphorylation.

For comparison, nuclear DNA in humans has 3 billion base pairs, coding for 20000 proteins, with the vast majority of the DNA being non-coding (regulatory sequences, etc.).
