Description The replication of prokaryotes can be divided into three phases, B C and D, while there are multi-rounds of replication happened in one cell. So both the phase and the copy number of genome is various in a culture.
Our problem arises from a research about constructing 4D genome of eukaryote. So we begin to wonder why there isn’t a 4D genome project of prokaryote. After research we find that due to its complicated replication mechanism, there will be a huge noise while detecting its structure, which hinder the research on prokaryotic genome.
Besides, the heterogenicity of cells are gathering importance recently in different fields.
Therefore we begin to think if there could be a methods to eliminate the heterogeneity. While thinking deeper into this problem, it becomes interesting that what would happen if all the cells are synchronized, will there be a new phenomenon that can change the traditional statements?
So in our mind the ideal synchronization methods should be not only simply inhibit the cell cycle but at the same time can free the inhibition according to our decision. As we all know, the manipulation of machine is much more accurate than hum beings, and there is a trend to let machine help us to control the organisms, so we want our synchronization system can also be controlled by machine, by program.
