Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

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 ...

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 ...

Top: Chromosome separate with functioning SMC in two models, line drawing and filled-space. The red and pink dots indicate, respectively, ori on each copy of DNA. Bottom: DNA separating without ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

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 ...

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 ...

A research team from Skoltech, the Institute of Physical, Chemical, and Biological Problems of Soil Science of the Russian Academy of Sciences, and other scientific organizations in Russia and the U.S ...
