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).

Study provides clues for designing more effective antiviral drugs

An international research team from the University of Turku based in Finland and PennState University based in the United States has solved an ancient puzzle of how living organisms differentiate between DNA and RNA building blocks at the time of gene expression, offering new possibilities for designing novel antiviral medications.

New highly sensitive RNA detection method advances in situ transcriptomics

Human cells typically transcribe half of their roughly 20,000 genes into RNA molecules at any given time. Just like with proteins, the function of those RNA species not only relies on their abundance but also their precise localization within the 3D space of each cell.

Decades of crop breeding prevents modern corn from recruiting nitrogen-fixing microbes

Corn didn't start out as the powerhouse crop it is today. No, for most of the thousands of years it was undergoing domestication and improvement, corn grew humbly within the limits of what the environment and smallholder farmers could provide.
