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).

Stem cell transplantation leaves no scars in the DNA of transplanted cells

Stem cell transplants do not lead to changes in the DNA of the donor cells. That's according to a new study, which provides important evidence for the safety of this procedure.

Researchers discover the role of a retrotransposon in horizontal memory transfer in roundworms

When an organism encounters a threat in its environment, it is to the species' advantage to warn others of the peril.

Miniature CRISPR-Cas system expands applicability and implications further

For the first time, Stanford researchers have miniaturized CRISPR for mammalian gene editing, which magnifies the scope of CRISPR technology.

UMSOM study suggests a genetic basis behind instantaneous human compatibility

Have you ever met someone you instantly liked, or at other times, someone who you knew immediately that you did not want to be friends with, although you did not know why?

Experts decode the genetic mechanism governing the speed of mRNA translation

The genetic material of all eukaryotic organisms is stored in the cell nucleus in the form of DNA. The DNA is first transcribed into messenger RNA in the cell cytoplasm and later translated into protein using ribosomes for it to be used, where ribosomes are small machines capable of decoding messenger RNA to synthesize the relevant proteins.

New approach to enhance cell-free biosynthesis with engineered yeast extracts

Think of cells as tiny factories: within their walls they have both the machinery to make products such as proteins, and the mechanisms for maintenance to keep processes running smoothly.

New approach could lead to better treatments for mitochondrial diseases

Mutant DNA sequences inside cellular mitochondria can be eliminated using a bespoke chemical compound. The approach, developed by scientists at Kyoto University's Institute for Integrated Cell-Material Science (iCeMS) in Japan, could lead to better treatments for mitochondrial diseases.

Massive study identifies 579 genomic locations linked to self-regulating behaviors

Researchers have identified 579 locations in the human genome associated with a predisposition to self-regulation-related behaviors, including addiction and child behavioral problems. With data from 1.5 million people of European descent, the effort is considered to be one of the largest genome-wide association studies to date.

Researchers use DNA barcoding to authenticate 'wild mushrooms' in food products

Harvesting wild mushrooms requires an expert eye to distinguish between the delicious and the inedible. Misidentification can have a range of consequences, from a disgusting taste and mild illness to organ failure and even death.

Genome editing tool used to render male mosquitoes infertile and slow disease spread

Mosquitos spread viruses that cause potentially deadly diseases such as Zika, dengue fever and yellow fever. New U.S. Army-funded research uses gene editing to render certain male mosquitoes infertile and slow the spread of these diseases.

New CRISPR-based technique for rapid screening of hundreds of genes in a single experiment

Zebrafish- small, fast-growing creatures who share many of the same genes as humans- are instrumental to many biologists, who find them uniquely well suited for studying a wide range of questions, from how organisms develop to how the nervous system drives behavior.
