Putting the brakes on evolution

... "Hurst's research focused on short sequences of DNA where such a second code exists and acts as a 'splice enhancer'. After DNA is copied into a molecule of RNA, these enhancers tell a human cell how to snip out unneeded sections and splice together the remainder, so it can be used as the template for protein production." ... "In the lab, it is possible to eliminate the need for splicing. So a DNA sequence could have its splicing function removed from it completely, and researchers could introduce genetic changes to produce a faster or stronger protein. Biotechnology researchers could perhaps use this technique to create more efficient enzymes." ... (link)

... "to create more efficient enzymes" ... Los otros días Laura me dijo que quería ser endocrinóloga, y los dos quedamos en que iba a ser una carrera con muchas inovaciones en los próximos años. ;)
