The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

DNA, which has a double-helix structure, can have many genetic mutations and variations. Credit: NIH When cells in the human body divide, they must first make accurate copies of their DNA. The DNA ...

The process begins by unzipping DNA's ladder-like structure, resulting in two strands called the leading and lagging strands. A molecular construction crew then assembles the missing halves of the ...

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 ...

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 ...

Homologous recombination is a DNA repair mechanism that counteracts double-stranded breaks in DNA. Researchers at Kindai University have recently revealed how the Sae2 protein coordinates with the ...

Ongoing research aims to confirm the mechanism by which ICP4 fluidizes the nucleus, which could indicate specific targets to counter viral replication.

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 ...

Maize serves as a vital model species for advancing our understanding of plant biology, yet many mysteries remain about the intricate processes ...
