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).

Cell division and its role in cancer development

To replace aging and worn cells, the body primarily uses a process called mitosis, in which one cell divides into two. When a cell is ready to divide, it duplicates its DNA so a complete copy is available for each of the daughter cells.

Coronaviruses represent a source of pandemic viruses

In a new paper published on the preprint journal bioRxiv in April 2020, researcher T. Konishi argues that the coronavirus family is a constellation of pandemic pathogens, that includes the currently spreading severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Researchers describe an underlying biological basis for mylagic encephalomyelitis/chronic fatigue syndrome

Mylagic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disabling and complex illness. Affected persons often cannot pursue ordinary activities -- physical or mental -- because of an incapacitating loss of energy and other symptoms, and may find themselves confined to bed or house-bound for years.
