In each cell of your body, DNA is stored in structures called chromosomes. When cells divide, these chromosomes are copied, ...

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 ...

Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division - a discovery that could lead to new cancer therapies, according ...

CDT1 inhibits the helicase activity of the MCM complex, thereby suppressing nascent strand synthesis in DNA replication in cultured human cells. This action results in fork collapse and DNA damage, ...

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 ...

Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...

An illustration shows a strand of engineered DNA passing through a nanoscale sensor, where its physical structure can be decoded as digital information. DNA nanostructures could one day serve as ultra ...
