When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...

DNA replication is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

DNA is a biological molecule that contains the instructions an organism needs to function, develop, and reproduce. It is present in all forms of life on earth and contains each organism’s genetic code ...

Within the nucleus of every cell are long strings of DNA, the code that holds all the information needed to make and control every cell within a living organism. DNA, which stands for deoxyribonucleic ...

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 DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break-when both sides of the DNA helix are cut at once.

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

When something goes wrong during DNA replication, cells call their own version of 911 to pause the process and fix the problem -- a failsafe that is critical to maintaining health and staving off ...

DNA methylation is a key epigenome component that helps dictate how genes are expressed, contributing to normal cell and tissue differentiation during development, as well as the process of biological ...
