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 ...

Mitochondrial transcription elongation factor maintains the balance between transcription and replication of mitochondrial DNA offering insights into potential treatments for mitochondrial disease and ...

Each human telomere is composed of 10-15 kb of repetitive DNA bound by a protein complex called shelterin, which forms a protective nucleoprotein cap at the chromosome end. In addition to shelterin, ...

DNA replication origins serve as sites of replicative helicase loading. In all eukaryotes, the six-subunit origin recognition complex (Orc1-6; ORC) recognizes the replication origin. During late ...

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 ...

Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and ...

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 ...
