The basic steps involved in DNA replication are known. The first step involves unzipping the intertwined double helix DNA structure, creating a "Y" shape known as a replication fork. These two ...

Z-DNA has a left-handed double helix structure. It is said to be found during the start of a gene. DNA replication occurs in the S phase of the cell cycle. DNA replication is the process where ...

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such ...

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot.

In July 2022, the World Health Organization (WHO) announced that monkeypox was a public health emergency of international concern. And, as of early December 2022, more than 82,000 human monkeypox ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...
