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 ...

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 ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that quantitatively detects and maps reversed DNA replication forks with ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...

From the first unzip of the double helix to the final joining of DNA fragments, replication is a carefully coordinated process. Understanding it helps explain how life preserves its genetic code with ...
