Transcript of Zebra Fish and genes

Zebra Fish and Gene Switches Scientists have succeeded in switching the genes of zebra fish. This research could help further unify biology and genomics by describing the interrelations of DNA, gene function and gene-protein expression and migration. The work could help shed light on health-related problems such as how cancerous cells spread, what makes some people more prone to heart attacks, or how genes factor in addiction. The study examines protein expression and function from 350 loci among the zebrafish's approximately 25,000 protein-encoding genes. The research yielded the first collection of conditional mutant alleles outside the Fishes DNA "Using a technique developed at the University in 2000 that allowed them to knock down, or turn off, specific genes, the researchers identified new genes that are implicated in the development of different systems and processes, such as blood and blood vessel development, formation of the eyes and ears, and metabolism of lipids, or fats."
