WebDuring synapsis, the nucleoprotein filament forms a joint molecule between the invading single-stranded DNA and the double-stranded DNA template molecule. This occurs at locations on the template homologous to the invading sequence through a rather mysterious step deterministically known as the search for homology (Fig. 2 ).
