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).

Gene Transcription Start Sites Identified as Hidden Mutational Hotspots

Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we study genetics and disease.

Mitochondrial Mutation Found to Rewire Immune Function

Scientists have discovered how a mitochondrial mutation rewires immune function in a model of inherited primary mitochondrial disorders, which often lead to severe disability and death.

Scientists Uncover Inner Workings of Biomolecular Condensates Linked to ALS

Inside the cell reside many tiny assembly factories and warehouses that gather together all of the proteins and RNAs-which carry out instructions from our DNA-that a living being needs.

DNA Rigidity Inside the Nucleosome Regulates INO80 Positioning

Researchers at The University of Texas MD Anderson Cancer Center have shown that DNA inflexibility, or rigidity, inside the nucleosome regulates the positioning of INO80. This highlights that the physical structure and shape of DNA, not just genetic information, are key components of DNA transcription.

Scientists Reveal How Memory T Cells Persist Across the Body

Memory T cells are a special type of white blood cell that "remember" past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again.

Old Blood Stem Cells Regain Regenerative Capacity Through Lysosomal Intervention

Researchers at the Icahn School of Medicine at Mount Sinai have discovered how to reverse aging in blood-forming stem cells in mice by correcting defects in the stem cell's lysosomes.

Novel Mechanism for Epigenetic Patterning in Plants

Every cell within an organism shares an identical genetic blueprint. Their distinct identities stem from epigenetics—precise chemical markers that dictate gene expression.

Bacteriophages Facilitate the Survival of Lactic Acid Bacteria in Kimchi Fermentation

The World Institute of Kimchi (President: Hae Choon Chang), a government-funded research institute under the Ministry of Science and ICT, has confirmed in a new study that bacteriophages, which were previously considered a 'nuisance' during the process of food fermentation, actually play the role of key helpers that facilitate the survival of lactic acid bacteria (LAB).

Discovery Reveals Greater Epigenetic Complexity in Unicellular Life

Multicellular organisms (animals, plants, human) all have the ability to methylate the cytosine © base in their DNA. This process, a type of epigenetic modification, plays an important role in conditions such as cancer and processes such as aging.
