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 ...

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 ...

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 ...

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 ...

Every living thing has DNA, the blueprint for life. These genetic blueprints separate us as species and, further, as individuals. The human genome — the complete set of DNA found in all humans — is ...

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 ...

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 ...
