When double-stranded dna is heated to 95°c, the bonds between complementary base pairs break to produce single-stranded dna. considering this observation, is the strand separation step required for replication of the double helix spontaneous? why or why not?

Single-stranded DNA is produced during all aspects of DNA metabolism: replication, recombination, and repair. No. A continuous input of energy is required. Chemical reactions are spontaneous if they can proceed on their own, without any continuous external influence such as added energy (in this case heat).

The answer is c : ) hope this answered your question!
