Mutation of FT by Sato
FT gene has two BioBrick restriction enzyme sites, EcoR1 and Pst1 which is next to each other.
So we tried to delete both at once by using two primers with mutation.

Golden Gate Assembly

August 10

Golden Gate Assembly method This method helps us to constract some genes quickly and we can design the order of constractions. We are trying to construct a gene cycle composed of 6 genes( pSB1A3, lacI, GFP, RFP, GFP, DT). After this experiment is confirmed to work, we will so some experiment to check how the numbers of promorters influences the strength of transcription.
