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 ...

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 ...

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, ...

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

Researchers have identified a molecular brake that limits DNA replication in healthy cells, revealing how cells prevent a long-suspected replication catastrophe and pointing to a potential ...

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 ...

Focusing on the schematic illustration in a, two DNA polymerase molecules are active at the fork at any one time. One moves continuously to produce the new daughter DNA molecule on the leading strand, ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by researchers at Goethe University Frankfurt, part of the Rhine-Main University ...

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, ...
