So now we've looked the past road blocks the spider silk use, that it evolution into a feasible resource thanks to Web and Pete here. Let's examine the process by which the spider gene was passed to the goats. According to the January 15th, 2006 issue of the Journal Nature, "Spider silk starts out as a substance called sclero protein which shoots out from the spider's web spinnerets seen here and dries into a thread. When this thread hardens we end up with something that looks a little more familiar to us." When it was discovered by Nexia that the silk gland of spiders were similar to that of a goat's mammary glands, Nexia took the research they discovered and applied it to dairy goats. By taking a goat embryo, Nexia inject the spider gene into the goat's mammary cells, these cells will then take effect and activate the female goats when they start lactating or gathering milk for their young.
