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).

Taste trumps everything, despite some hesitation about gene-edited table grapes

Despite some hesitation about gene-edited foods, taste trumps everything, according to a Washington State University-led survey of U.S. consumers.

Scandinavian gene pool development via DNA analysis

The complex relationships between geography, ancestry, and gene flow in Scandinavia are resolved in a new study based on 297 ancient Scandinavian genomes that were analyzed along with the genomic data of 16,638 modern Scandinavians.

Researchers expand the known defensive abilities of CRISPR–Cas systems

Viruses can infect bacteria and archaea, just as they can humans. These microbes have evolved their own immune defense mechanisms to combat their pathogens. Bacterial defenses, like CRISPR-Cas systems, contain a variety of proteins and functions that aid bacteria in protecting themselves from foreign intruders.

The detrimental effects of alcohol consumption during pregnancy

For the first time, researchers at the University of Helsinki in Finland examined the effects of prenatal alcohol exposure on the epigenome and gene function of the placenta. The epigenome is a molecular coating on a DNA strand that controls how genes are expressed.

Uncovering new function for small RNAs in Salmonella infections

Millions of people get sick from Salmonella each year because they are food-borne pathogens. These bacteria rely on a sophisticated network of genes and gene products that give them the ability to sense environmental conditions to do this.

Analysis of genetic factors contributing to cleft lip and palate

Cleft lip and palate, which are mainly caused by genetic reasons, are two of the most common congenital malformations. It is still unknown which genes are exactly affected.

RXR: A key protein in the balanced production of different blood cells

In the regulation of hematopoietic stem cells—which are the immature stem cells that produce all the blood cell lineages—the cell protein retinoid X receptor (RXR) is an important element.

Researchers gain insights into how density may change gene expression in some insects

A grasshopper hatched in a crowded environment may look and behave differently than a grasshopper hatched in isolation -; even if they have the same genes.

Using CRISPR technology to reduce the symptoms of Huntington’s disease

A neurological condition called Huntington's disease (HD) results in a progressive decline in movement, coordination, and mental ability. It is brought on by a mutation in the huntingtin, or HTT, gene.

Molecular regulation underlying emergency hematopoiesis uncovered

If the body’s emergency hematopoiesis program activates, it signifies an alert state of the immune system and serves two functions: In comparison to “normal mode” hematopoiesis, the emergency program results in enhanced replacement of immune cells consumed during infections or inflammations.
