DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Silver nanoparticles enable precise DNA cutting and assembly

DNA is composed of long chains that act as the blueprint for living organisms. In genetic engineering, scientists cut DNA at specific sites and join the resulting fragments to other DNA sequences, enabling applications such as advanced crop breeding, genetic disease treatment, and the generation of animal models for drug discovery.

New study frames altered protein modifications as cancer drivers

Cancer has often been explained through mutations in deoxyribonucleic acid (DNA) or changes in ribonucleic acid (RNA), but these layers do not fully explain why tumors with similar genetic profiles can behave differently.

Uninherited parental genes leave lasting imprint on children's lives

Our parents' genes, even the ones we didn't inherit, leave a measurable lasting imprint on our lives. An international team led by researchers at the Institute of Science and Technology Austria (ISTA) and the Norwegian Institute of Public Health developed a new approach to analyze genetic data from tens of thousands of families.

New non-invasive tool lowers cancer DNA tracking threshold to 5%

Blood tests have proved to be a promising tool for detecting and monitoring cancer. Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have now developed a new method that makes it possible to analyze samples containing as little as 5 per cent cancer DNA in the blood, compared with the 15–20 per cent required today. This method could lead to better cancer care and improved monitoring of tumor progression.
