Spiders and Silkworms – a Silky Story 11/01/12

Spiders and silkworms have had a recent DNA swap!

Working in collaboration with each other, scientists from three labs have managed to put the silk making part of spider DNA into a silkworm’s genome.  Now the silkworms are able to produce spider silk which is very strong and elastic instead of their own silk which is very delicate.

They reason why they are not using spiders to produce spider silk is that they are too cannibalistic to keep and farm together and would eat each other. The transgenic silk will be used in artificial ligaments, tendons, tissues scaffolds and cosmetics.
