The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

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) ...

A team of researchers at the University Medical Center Schleswig-Holstein (UKSH), Kiel Campus, the Kiel University, and the ...

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 ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...

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 ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...
