Biology for the majority of those good old biology. A biology is one of biology

Biology for the majority of those good old biology. A biology is one of biology's more. New biology have different names: synthetic biology, stem cell biology, systems biology ... No longer that old biology. spiders Time goes on.
One of the most prominent Canadian newspaper The Globe and Mail (Toronto, which dates back 165 years) last week announced that just before approval for use in human first genetically spiders modified animal. It will not be cattle, as some have suggested, but salmon. U.S. biotech spiders company Aqua Bounty Technologies has developed Atlantic salmon gaining weight twice as fast as natural. This will mean an increase in production and its cheaper, the quality of meat is expected to remain unchanged, they say. With the technology developed by Canadian researchers are Atlantic salmon installed genes from Pacific salmon called Cavic and the American nematode that lives in the cold waters of the Atlantic. Cavic did more than Atlantic salmon and its relative, the nematode is phylogenetically somewhat more distant. It is known that the production of proteins, which act as antifreeze and allow the fish is also active spiders in the very cold water. Genetically modified salmon would have been able to intensive feeding in winter and could even gaining weight, spiders which is an important factor in salmon farms. According to some other data (1) are referred to U.S. nematodes take a promoter, so that its expression is no longer dependent on the light, and it is synthesized throughout the year. From Čavić to the genes for growth hormone (2). Canadians fear that approval of genetically modified spiders salmon for consumption in the United States put pressure on Canada to take the same decision, although many predict adverse spiders reactions to any approval. spiders The biggest concern is the issue of possible GM salmon escapes from the networks in which they grow in the sea, which could be mated with natural salmon and thereby nelastne transfer genes to wild populations of fish. The problem is solved in such a way to be the SG salmon farming only triploid females, who do not develop ovarian and are therefore sterile. Although an application has been filed for approval in 1996, a final positive opinion yet, assume that it will happen this year.
