Spiders genetically merged with Goats

Spiders genetically merged with Goats

クモは、ヤギと遺伝的に結合しました

A certain goat farm in Quebec requires visitors to shower and put on white coveralls and booties before being allowed to look at the animals. These special goats have been genetically engineered to produce spider silk in their milk. This of course raises the question, why would anyone want a goat to make spider silk?



Science Nation - Got Silk?

Since the time of the ancient Greeks, humans have been using spider silk to dress wounds. Scientists now know spider webs not only have healing qualities, they can be stronger than steel! University of Wyoming Molecular Biologist Randy Lewis adds an almost science fiction aspect to the study of spider silk : making large quantities of it by, "growing it," in goat's milk. With funding from the National Science Foundation, Lewis has cloned and sequenced genes for the proteins that make up five different spider silks, some stronger than Kevlar, other more elastic than nylon. Spider silk is also antimicrobial, hypoallergenic and completely biodegradable. The gene for, "spider dragline silk," has been introduced into the cells of goats by non-viral methods. The goats excrete the spider silk protein in their milk. Several goats with this gene were born in Lewis' lab in late January 2010.

Got Silk? -- Biotech Applications

Imagine spinning goat milk into spider silk five times stronger than steel! Scientists have found a way to put a whole new spin on genetic research. It's called biomimicry. Scientists are now able to mimic a spider's web by breeding goats with spider genes in their mammary cells. The goat's milk contains a protein that can be spun and stretched into a fine silk fit to cover Spiderman -- the spidergoat is here.

All 50 Secrets of the Sequence videos have an accompanying classroom-tested lesson that encourages students to further explore the video topics. Each lesson includes background information, state and national science standards, discussion questions and answers, teacher notes and an activity that will ensure a hands-on, "minds-on" experience.
