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.
Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains (Figure 1).
