Gene drives spread chosen genes through populations of sexually-reproducing organisms with short lifespans. For example, scientists could potentially use gene drives to spread a gene through many, many, many mosquitoes to stop them from transmitting malaria. While gene drives would not work ...
WebA gene mutation is a change in the gene’s DNA sequence and is not to be confused with gene knockdown. Scientists often intentionally introduce specific mutations in cells for research. Basic molecular biology techniques have enabled scientists to do this for several decades in some cell types, especially bacteria and yeast.
