It was previously thought that, in bacteria, the growth-dependent accumulation of active DnaA provided a universal mechanism to couple growth with DNA replication initiation. However, as Levin and ...

During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a ...

During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these ...

Additionally, the scientists unexpectedly captured for the first time a detailed picture of how the "engine" driving the ...
