How can we design new DNA? (Frances Arnold)
Science Kit for Frances Arnold
I'm glad you are interested in my talk and want to find out more. My Caltech laboratory maintains a website where you can read more about directed evolution (and sex with molecules). You can also find most of our published papers there, including some versions that you can download.
A publication on breeding cellulase enzymes for making biofuels can be found here: http://www.che.caltech.edu/groups/fha/publications/PNAS-2009-Heinzelman-0901417106.pdf
And a publication describing new cytochrome P450s evolved in the laboratory can be found here: http://www.che.caltech.edu/groups/fha/publications/sawayama_cej_2009.pdf
(These are just examples, there are many more at the lab website.)
If you want to read an in-depth review of our directed evolution work, I recommend: http://www.che.caltech.edu/groups/fha/publications/Romero_NRMCB2009.pdf
And if you want to read a more personal essay on evolution and molecules, check this out: http://www.che.caltech.edu/groups/fha/publications/Arnold_Microbe2011.pdf
Enjoy your own explorations of the benefits of sex and evolution!
