DNA replication is the process by which a cell makes an identical copy of its DNA. This process is performed at the beginning of every cell division so that when the cell divides, each daughter cell ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

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 ...

Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment has been the focus of a 30-year research question. New work from the Crick ...

So-called junk DNA was given that unfortunate nickname because its function was so mysterious. These vast regions of the genome do not code for protein and are made up of highly repetitive sequences.

The Polymerase Chain Reaction (PCR) is a technique for the amplification of DNA in vitro (this describes experiments with cells outside their normal environment). PCR amplifies DNA using complementary ...
