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).

Uncovering the Genetic Basis of Sex Determination in Amborella trichopoda

Although it is a complicated process, plant reproduction is essential to both ecological balance and the food chain. Some plants are hermaphrodites, some are either male or female, and some change sex during their lives.

Novel Genetic Variant Associated with Severe Mitochondrial Dysfunction

The rare hereditary condition known as mitochondrial DNA depletion syndrome (MTDPS) is typified by a significant reduction in mitochondrial DNA (mtDNA).

New Method for Understanding Brain Function and Dysfunction

An international group of researchers from FutureNeuro, the Research Ireland Centre for Translational Brain Science, and RCSI University of Medicine and Health Sciences have created a novel technique to characterize gene activity in the living human brain.

Overlapping Enhancers Challenge Traditional Genetic Models

The DNA of plants and animals contains their blueprint. However, genes, which are the instructions for generating proteins, are found in a very small portion of the genome roughly 2% in mammals.

Self-Eliminating e-Drive System Reverses Insecticide Resistance in Fruit Flies

Insecticides have been used for centuries to counteract widespread pest damage to valuable food crops. Eventually, over time, beetles, moths, flies and other insects develop genetic mutations that render the insecticide chemicals ineffective.

Ancient DNA Unlocks Secrets of European Genetic Adaptation

Leveraging a unique statistical analysis and applying it to ancient DNA extracted from human skeletal remains, a team of researchers from The University of Texas at Austin and the University of California, Los Angeles has revealed new insights into how ancient Europeans adapted to their environments over 7,000 years of European history.

Discovery of Large Tandem Duplications Opens New Avenues for Cancer Treatment

Cancer researchers at the University of Chicago and the University of California, San Francisco (UCSF) have discovered that mutations in certain genes can lead to the accumulation of DNA errors, resulting in a specific type of genetic change known as large tandem duplications (TDs) that can arise from the collision of two critical cellular processes: transcription and DNA replication.
