Cornell researchers have answered a fundamental question about how two strands of DNA separate to start a process called replication, in which genes copy themselves. The research examined the role of an enzyme called a helicase, which plays a major role in separating DNA strands. Share: FULL STORY.
The hydrogen bonds (holding together complementary bases) break and part of the double helix separates. Strand separation is required for transcription (copying DNA to RNA) and replication (copying DNA to DNA). In the figure below, the yellow strands have separated allowing the molecule to relax and assume a circular configuration.
