Cartoon comparing DNA strand displacement using the DNA-tweezers (top) versus the DNA probe built into the previous chip (bottom). Disclaimer: AAAS and EurekAlert! are not responsible for the ...

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 ...

A study links the loss of DNA methylation across the genome—as is common in cancer—to the disruption of the 3-D compartments that organize the genome and to the timing of DNA replication. Cell lines ...

While scientists have long known the importance of helicase in DNA replication, "they did not know how DNA, helicases and ATP work together in a coordinated cycle to drive DNA unwinding," De ...

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