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 finds similar levels of DNA damage in vapers and smokers

Engineering a phage's DNA by introducing modified CRISPR-Cas machinery genes

Bacteriophages (or phages) are viruses that infect bacteria. They are the most abundant biological entity, and they can be found wherever bacteria live. To propagate themselves, phages inject their DNA into their bacterial hosts.

DNA analysis reveals the existence of juvenile coastal cod off the west coast of Sweden

The rumor that the coastal cod is extinct is not true. Through DNA analysis, researchers at the University of Gothenburg have identified that there are still juvenile coastal cod off the west coast of Sweden. However, it is still difficult to find any mature adult cod in the area.

Researchers report the genome-wide atlas of chromatin-accessibility during stomatal development

Researchers at Nagoya University in Japan, the University of Texas at Austin, and the University of Washington have elucidated a mechanism that makes tiny plant stem cells destined to give rise to stomata, cellular valves of plants that facilitate global carbon cycles.
