If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

Enzymes, which are crucial to controlling how cells replicate in the human body, could be the very ingredient that encourages DNA to spontaneously mutate -- causing potentially permanent genetic ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

Although DNA is tightly packed and safeguarded within the cell nucleus, it remains continually at risk of damage from normal ...

A new family of enzymes enables precise cuts in single-stranded DNA, offering powerful new tools for genetic engineering and expanding possibilities in biotechnology. (Nanowerk News) A few years ago, ...

BRCA1 (BReast CAncer Gene 1), a key gene that becomes faulty in some instances, leading to breast and ovarian cancer, plays an important role in the body's DNA repair mechanisms. BRCA1, once mutated, ...

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 ...
