Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

DNA replication is a tightly controlled process that copies the genetic code, allowing its instructions to be conveyed from one generation of cells to the next. In diseases like cancer, these ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the ...

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

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

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

The Smolka Lab, led by Prof. Marcus Smolka, molecular biology and genetics, recently published a study shedding light on a novel pathway that explains how cancer cells can become resistant to ...

A new study has uncovered a hidden step that helps the deadliest malaria parasite survive and multiply inside the human body.

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 ...
