Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists ...

Researchers at California NanoSystems Institute at UCLA, Stockholm University and Uppsala University are working on a smartphone-based microscope in hopes of developing a cost-effective and accessible ...

Current genetic sequencing techniques can provide much information about the genetic makeup and activity in a sample, like a piece of tissue or a drop of blood. But they are unable to reveal where ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...

Paras Gaur, a postdoctoral researcher at the University of Iowa, investigates DNA damage repair and G-quadruplex structures ...

Cells are the smallest units of life. But even within the same tissue or organ, they are not all identical. New variations arise continuously during cell proliferation. While genetic mutations alter ...

During replication, DNA polymerases are positioned on each strand of DNA . Using a microscope slide as an anchor, we tethered DNA to a bead and stretched it with a flow of solution. We tracked how the ...
