California biotech companies such as LS9 and Amyris have ploughed millions of dollars into developing synthetic organisms that will produce diesel. Again, though, this is all still slightly theoretical. But all spiders produce silk. Also, using natural spider silk to create an object is time-consuming and quite tricky. Some spiders produce a silk that is low in UV reflection and is also translucent, so insects cant see it, says Catherine Craig, an evolutionary biologist and author of Spider Silk: Evolution and 400 Million Years of Spinning, Waiting, Snagging, and Mating. But when the spider needs to travel along the sticky threads of its web, it has a special tool: tiny claws on its legs help it keep from getting stuck. There are four types of bases in the nucleotide of DNA: adenine (A), thymine (T), guanine (G) and cytosine (C). Some spiders can produce more than one type of silk.

Last summer, in suburban Sunnyvale, California, I hung out at a gathering of synthetic biology weekend hobbyists, self-styled as "bio-hackers" with the excellent name BioCurious. Hes the subject of a young adult non-fiction book called Stronger than Steel, and Al Gore referenced his research in an NPR interview this year. Scientists are often confounded by baffling "noise" in the molecules that make up living organisms, unpredictable variation set among unfathomable sophistication. (Read about the spider that uses its web to shoot itself faster than a rocket.). He and his team took the gene that encodes dragline silk from an orb-weaver spider and placed it among the DNA that prompts milk production in the udders. Here are more such interesting facts about Sparta. Prof Lewis said the team collected about four metres of silk for every four drops of protein they gathered. - As Spider Goat, if you use the Spider Web tongue up a wall, retract it completely, and then release it you should stick directly to the wall.

It can grow up to 11 inches wide, and its fangs are up to one inch long. 02 Over 45,000 species of spiders exist.

When spiders reproduce, they house their eggs in several sacs, each of which holds hundreds of eggs inside of it. The project has had robust funding because the properties of spider silk are highly desirable in a lot of waysit is even stronger than Kevlar. These proteins are released through the goat's milk.
