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 ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the ...

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

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible to the cellular machinery that works to express the right genes at the ...

An international collaborative research team has discovered that G-quadraplex DNA (G4-DNA) accumulates in neurons and dynamically controls the activation and repression of genes underlying long-term ...

How does DNA structure itself from the very first moments of life? A team of researchers has just observed that DNA adopts a defined three-dimensional architecture much more rapidly than ...

Diagrams: Short section of DNA, 1951 -- Chemical structures of the DNA bases, 1951 -- Covalent bonds of the sugar-phosphate backbone -- Schematic view of a nucleotide -- Mg** ions binding phosphate ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team. DNA is widely accepted to be formed of two strands that wind around one ...
