Re: How did endosymbionts coordinate replication?

... So, I suppose, in any eukaryotic cell the mtDNA should be relatively conserved. However, the mutational rate of mtDNA is ten fold higher than that of nuclear DNA. So is the mtDNA sequence conserved among e.g. various mammalian species or the opposite?

Why would the identical amino acids region of certain specie

OK, so you have DNA sequences from related species which are somewhere diverse, somewhere are identical. For example the region coding for active site will be probably conserved, while some loops on surface of the protein will be divergent. Both on DNA and amino ...
