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.
Very often, scientists use enzymes to cutâor digest, as it is calledâthese large strands of DNA. into smaller segments. These smaller segments can then be studied in a variety of ways. One very useful activity, called gel electrophoresis, allows a scientist to easily separate fragments of DNA by size.
