Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that ...

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...

In the past few years, gel electrophoresis of DNA fragments has become an important complement to hybridization and amplification sequencing tools. As variations on PCR, RFLP, mutation sequencing, and ...

Research team led by Nagoya University develop a label-free method for detecting DNA amplification in real time based on refractive index changes in diffracted light. Polymerase chain reaction (PCR) ...

Drs Ursula A. Matulonis and Joyce F. Liu discuss targeting DNA damage and repair and replication stress in endometrial cancer. Drs Ursula A. Matulonis and Panagiotis A. Konstantinopoulos discuss ...
