DNA resequencing DNA resequencing was the region - specific manipulation of the genetic structure of an individual . DNA resequencing for any reason other than repairing serious birth defect s was illegal in the Federation . In 2154 , the Klingon s used embryo s from genetically - engineered Human Augment s to resequence a number of test subjects . Unfortunately , there were some unanticipated side effects , including the dissolving of their cranial ridges . Augment DNA was found to be more aggressive than the Klingons realized ; nevertheless , the test subjects became stronger and more intelligent before their neural pathway s unexpectedly started to degrade , and they died in agony ( see Klingon Augments ) . ( ) In 2348 , Julian Bashir , a Human from Earth , illegally received a form of DNA resequencing on Adigeon Prime known technically as accelerated critical neural pathway formation . These " treatments " accelerated the growth of neuronal networks in his cerebral cortex , enhancing his mental abilities and allowing his intelligence quotient to jump five points a day for over two weeks . Further " treatments " led to improvements in his hand - eye coordination , reflex es , vision , stamina , height , and weight . ( ) Unlike the Bashir family , other Human families who attempted to have their children ' s DNA illegally resequenced did not find doctor s as competent . Many suffered unintended side - effects , including the children , Patrick , Lauren , and Sarina Douglas . By the time they were five or six years old , their parents had to come forward and admit that they ' d broken the law so their children could get treatment . There was not much the doctors at the Institute could do for them , since cases like theirs were so rare there was no standard treatment . ( ) In the case of Sarina Douglas , her parents had her cerebral cortex genetically enhanced in order to accelerate the rate at which she processed information . Unfortunately , a complication in the procedure occurred , and her visual and auditory systems were out of sync ; thus , she was unable to channel stimuli into her cortex fast enough , and therefore unable to focus on what was going on around her . This was corrected by Dr . Bashir in 2375 , when he sped up her sensory processes by stimulating the growth of new synapse s in her thalamus . He accomplished this by manipulating her neural protein s at the subatomic level . ( ) In early - 2370 , the Ferengi Bok used genetic resequencing to alter the DNA of a Human named Jason Vigo in order to convince Jean - Luc Picard that Vigo was his son . Bok ' s technique , however , was flawed and Vigo began to suffer from a neurological disorder called Forrester - Trent Syndrome . Dr . Crusher investigated its cause and upon concluding a microcellular scan , she discovered Bok ' s deceit . After a series of treatments to Vigo , Dr . Crusher was able to completely reverse the effects of Bok ' s botched attempt . ( ) In 2374 , The Doctor created a genetic resequencing vector to neutralize Borg nanoprobe s . ( ) In 2377 , Icheb proposed genetic resequencing to The Doctor as a means of regulating his body ' s Borg implants without having to rely on his cortical node . Icheb wished to donate his cortical node to Seven of Nine in order to save her life . ( ) 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 .
