Scientists Invent Faster Gene Function Identification System
...though approximately 70 to 80 percent of the human genome
has beensequenced, gene identification is moving at a much slower pace, Wagner says.Using conventional methods, genes cannot be identified until their entiresequence is known. The sequence information is used to generate transgenicanimals in which th...
