Project Description/Abstract

Notes

• Our review paper on genetically encoded memory (in preparation)
• Summary note on site-specific recombinase
• List of site-specific recombinase
• Presentation: writing to DNA (present to Infinite Monkey Theorem Group, 11/01/98)

Outline

1. Application
2. Grand Challenges
3. Start-up experiments
4. Review Articles

Project List

• Synthetic Jumping DNA from Integrase/excisionase system
• Implementing N-bit memory with DNA recombination
• Engineering cell-cycle reporter
• Quantitative functional profiles (Database) of site-specific recombinase
• Expanding Integrase/excisionase library

Conceptual questions

• In the abstract level, how could we live with imperfect efficiency? No matter writing mechanism we choose in the end, the fraction of cells whose genome is actually rewritten will likely to be significantly less than a hundred percent.
• What are the common/ different challenges between writing memory to DNA versus gene therapy/ transgenic?
• Why reaction of some DNA integration is irreversible but most other don't?

TO DO List

• reading
• Next meeting: mention storyboard on interesting paper
• Next meeting: mention DNA-pol in vitro selection and in vivo mutagenesis
• read the poster detail from synbio 4.0, esp memory
• Write up the detail structure and mechanism of integrase
• discuss HT-in vivo protein evolution project with Jennifer, James, Quake's pp
• Maybe I should start focusing on specific memory encoding problem..like counting the number of cell cycle.

..many signaling protein rise and fall in each cell cycle, so as the copy number of genome..we might be able to make use of them.
