His solution was polymerase chain reaction (PCR), a molecular technique that rapidly duplicates short, specific segments of DNA, transforming one fragment into millions of identical copies.

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 ...

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 ...

PCR-machines are used for replication of DNA, detecting DNA sequences, carrying out DNA fingerprinting, forensic analysis, and molecular cloning, diagnosing genetic diseases, and detecting ...

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

During DNA replication, the double helix unwinds ... and neurotransmitter release, in response to extracellular signals. PCR is a widely used technique for amplifying DNA segments. It relies on the ...

Chemotherapy drugs can kill cancer cells by halting DNA replication, but a glucose-depleted environment can help cancer cells overcome this effect and resist death. Sahana is a science journalist and ...
