DNA is a linear biopolymer, a compound biomolecule in the form of a double helix. Polymers are made of monomers, and in DNA, ...

In a groundbreaking shift in our understanding of mutations, researchers have discovered types of DNA damage in healthy cells that can remain unrepaired for years. While most types of DNA damage are ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows.

The building blocks of DNA have been found in samples returned to Earth from an asteroid, suggesting life rained down from ...

DNA forms loops to bring the enhancer (orange) and promoter (green) regions closer together so that the activator can affect the RNA polymerase and switch on the gene (pink and blue). Image made ...

This is important because some forms of cell death are unnoticed by ... "The surprising result of our research is that DNA repair, which normally protects healthy cells, determines how cancer ...
