Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

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 ...

Scientists reveal a hidden second layer of human DNA, showing how genome folding controls genes and influences disease development.

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 ...

Innovative study of DNA's hidden structures may open up new approaches for treatment and diagnosis of diseases, including cancer. DNA is well-known for its double helix shape. But the human genome ...

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 ...
