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).

Researchers discover a new epigenetic mark in small freshwater animals

Your DNA holds the blueprint to build your body, but it's a living document: Adjustments to the design can be made by epigenetic marks.

Genetic analysis reveals markers for predicting seed oil quality in Russian sunflower

Researchers from Skoltech and Pustovoit All-Russian Research Institute of Oil Crops performed a genetic analysis of Russian sunflower lines and identified genetic markers that can help to predict the composition of tocopherols, one of the key attributes of oil quality.

Researchers identify universal patterns in the chemistry of life

The only references we have for "life" are the forms we know on Earth. Astrobiologists suspect that the search for alien life, and even for the origins of life on Earth, may require a broader scope.

Study provides first genetic evidence of demographic changes among hunter-gatherer populations

A new analysis of ancient human DNA demonstrates that people moved and chose their reproductive partners along complex social networks that stretched across large swathes of Africa between 80,000 and 20,000 years ago, according to a study co-led by Yale anthropologist Jessica Thompson.

Scientists elucidate mechanism that causes treatment resistance in aggressive pancreatic cancer

Drug resistance is a major obstacle in the treatment of cancers. In an aggressive type of pancreatic cancer, for instance, drug resistance is associated with the suppression of programmed cell death, which results in the uncontrolled growth of cancer cells.

Study shows how 3D scaffolding of chromosomes is related across carnivore species

Studies comparing animal genomes generally focus on the DNA sequence itself. A new study by researchers at the University of California, Davis shows how the three-dimensional scaffolding of chromosomes is related across several species of carnivores, offering a new approach of "comparative scaffotyping" that could be used to identify related genes across species and place them in context.
