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, ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both ...

Before a cell divides and DNA is passed from one cell to another, a complex process occurs. The DNA strands unwind and separate. Each strand makes a complementary strand by adding the appropriate ...

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 ...

On 22 May 2019, scientists from Queen's University boarded a modified Falcon 20 aircraft at Ottawa airport. Scheduled was a ‘vomit comet’ flight, where the plane repeatedly climbs to 8km in a steep ...

The protein UBR7 acts as a histone chaperone, regulating histone re-deposition at specific sites during DNA replication, according a recent study published in The EMBO Journal. This protein was ...

Jennifer A. Surtees has long been dedicated to studying genome stability and boosting community involvement in research. With a new National Institutes of Health (NIH) grant, she’ll get to do both.
