WebThe cell cycle is an orderly sequence of events that describes the stages of a cell’s life from the division of a single parent cell to the production of two new daughter cells. The mechanisms involved in the cell cycle are highly regulated. Genomic DNA WebApr 7, 2024 · Their data showed that increasing the levels of the key regulator of chromosome segregation, ParA, gave the cells multiple replication starting points. The team has hypothesized that ParA’s ability to kickstart replication in Caulobacter crescentus is an indirect result of altered events throughout the cell cycle.
