This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

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 ...

Although it also performs some functions in men, estrogen, the main female sex hormone, is involved in a myriad of processes, ...

Researchers at the CNIO show that oestrogens regulate gene expression by changing DNA supercoiling. Hormone-activated ...

Using advanced imaging techniques and precise microfluidics control to stretch out curly DNA into a straight line, new research demonstrates techniques for stretching and immobilizing DNA with minimum ...

Estrogens, the main female sex hormone, although they also perform some functions in men, are involved in a myriad of ...

Two new tools created at Gladstone Institutes allow scientists to study DNA at single-molecule resolution using fewer cells than previously required, with clear applications for cancer and many other ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...
