This does not require environmental cycling and is not blocked by re-annealing. However, under non-enzymatic conditions, if strand-displacement occurs from a linear template, we expect the incomplete new strand to be almost always displaced by the tail end of the old strand through toehold-mediated displacement. A third kind of replication in viruses and viroids is rolling-circle replication which occurs via strand-displacement on a circular template. Rolling-circle replication does not require environmental cycling and is not prevented by toehold-
