In D-loop: 40 years of … Weblication, the D loop, that can be seen by electron microscopy (1). D loop formation occurs via the displacement of one of the strands (the H strand) of mtDNA in the region of the origin of replication by the synthesis of a short complementary piece of DNA, referred to as 7S DNA, the synthesis of which is termi-nated by an unknown mechanism.
