Researchers at the University of Toronto and partner hospitals have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy – a finding that could lead to new ...

Tuberculosis (TB) is one of the oldest and deadliest infectious diseases we know. It commonly impacts the lungs, but can also affect other areas of the body like the spine, brain or kidneys.

Picture in your mind a traditional "landline" telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

Researchers reveal how DNA gyrase resolves DNA entanglements. The findings not only provide novel insights into this fundamental biological mechanism but also have potential practical applications.

Fluorogenic DNA aptamers produce light only in the correct structural state, enabling programmable molecular logic, ...

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 ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Fear is an important survival mechanism and so too is the ability to inhibit fear when it’s no longer needed. In order to counter-balance fear, the brain engages in fear extinction. In this process, ...
