Researchers at the University of North Carolina (UNC) have discovered that a common lab molecule, used to label DNA, can trigger a runaway process that eventually leads to cell death. But the team ...

In the DNA fiber assay used in this study, cells labeled with IdU (green) and CldU (red) nucleotide analogs were sorted into substages of S phase before being subjected to the DNA fiber assay. This ...

Researchers have developed a new fluorescent label that gives a clearer picture of how DNA architecture is disrupted in cancer cells. The findings could improve cancer diagnoses for patients and ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During ...

Nanopore sensors are tiny devices used to detect and analyze individual molecules by measuring ionic changes as the molecules pass through nanometer-scale openings. These sensors are classified into ...

When bacterial DNA is labeled with radioactive atoms, it takes its own picture. Autoradiographs reveal that the bacterial chromosome is a single very long DNA molecule and show how it is duplicated ...

A label-free nanopore platform uses programmable DNA circuits to build versatile molecular logic gates, forming a universal basis for scalable DNA computing and advanced biosensing applications.

Single-molecule DNA detection using nanopore technology offers real-time analysis of DNA and RNA strands. It is a low-cost and flexible technique that can be used in clinical and research settings ...

Life scientists are striving to use the information emerging or obtained from the Human Genome Project to gain insight into basic biological processes and to improve human health and disease treatment ...
