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 unravels the mysteries of variation in microbiome composition

Oregon State University researchers have made a key advance in understanding how timing impacts the way microorganisms colonize plants, a step that could provide farmers an important tool to boost agricultural production.

Scientists gain insights into how parasitic bacterium gives rise to lesions

Bacteria of the genus Bartonella are parasites that can be transmitted to humans via insect bites and animal scratches, resulting in an infection known as "bartonellosis." Cat-scratch disease and trench fever are forms of bartonellosis caused by different Bartonella species infecting humans.
