DNA resequencing was the region-specific manipulation of the genetic structure of an individual. DNA resequencing for any reason other than repairing serious birth defects was illegal in the Federation. The "Institution" mentioned was never specified by name. In 2374, The Doctor created a genetic resequencing vector to neutralize Borg nanoprobes. (VOY: "The Raven") Also in 2377, when considering the procedure to make her and Tom Paris's baby less Klingon, B'Elanna Torres told him that genetic resequencing wasn't a weapon but rather a tool, like a hyperspanner.
