Outline of Annual Research Achievements |
During this FY, we achieved two main goals of our project. The first goal has been to develop a general theory to describe the DNA abundance distribution from the genome replication dynamics. This general theory constitutes the basis of our approach. The paper based on this theory has been published in Plos Computational Biology. The second goal has been to startup our wet lab activity and successfully run the first benchmark experiments on E.coli. This success puts us in a very good position for completing the rest of the project.

Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The research is progressing as planned, with one paper already published and the groundwork for future experimental activity already done. We expect to soon make progress on applying our theory and experiment to novel systems, in particular to E.coli mutants and other microbial species, as detailed in the proposal of this project.

Strategy for Future Research Activity |
During this fiscal year, we expect to finalize our project on studying DNA replication in engineered E.coli strains with multiple origins of replication. Motivated by our recent theoretical results, we will also apply our method to budding yeast, to prove that our approach is not limited to prokaryotic species. We expect to obtain at least preliminary results on this second goal during this fiscal year.
