In some situations a mitochondrion has both paternal and maternal alleles. This has two requirements: that both parents provide alleles to the zygote (which of course is not the

case when there is maternal inheritance.

Gyrases are A2B2 heterotetramers in which the B subunits bind and hydrolyze ATP and the A subunits mediate the double-strand cleavage, strand passage, and reunion reactions.

The eukaryotic type II topoisomerases are homologous to gyrases but with their A and B subunits fused so that they are homodimers.
