The term 'annealing' is often used to describe the binding of a DNA probe, or the binding of a primer to a DNA strand during a polymerase chain reaction. The term is also often used to describe the reformation (renaturation) of complementary strands that were separated by heat (thermally denatured). For example, proteins such as RAD52 can help DNA anneal. If at all possible, please annotate to the more specific terms GO:0036310 'annealing helicase activity', GO:0097098 'DNA/RNA hybrid annealing activity' or GO:0033592 'RNA strand annealing activity'.
