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).

First 'Living Digital Camera' Stores Images in DNA

In a world first, a 'biological camera' bypasses the constraints of current DNA storage methods, harnessing living cells and their inherent biological mechanisms to encode and store data.

The Mechanism of Immune Memory Development

The memory of the immune system depends on distinctive epigenetic traits and a particular 3D arrangement of the DNA in the nucleus of memory cells, allowing for rapid activation of these cells, according to a team of researchers from the Erasmus University Medical Center, the Centre for Genomic Regulation (CRG), and the Josep Carreras Leukaemia Research Institute.

New Insights Into How Genes Are Activated

Genetic information contained within DNA has to be read by specific proteins that enable the process of gene activation to begin – but in many cases, these proteins can't access their targets because DNA strands are bundled up to control what genes are used in the wide range of different cell types.

T cells are Sensitive to Genetic Disturbances Within Mitochondrial Power Plants

All cells have their own power plants, called mitochondria. There are often more than 100 mitochondria per cell and each possesses their own genome, which in turn contains genes responsible for energy production.

6mA Modification Genomic Distribution and Evolutionary Patterns in Plants

One of the epigenetic alterations is the amino acid N6-methyladenine (6mA). Although 6mA and 5-methylcytosine (5mC) were both found at the same time, eukaryotes have only lately begun to pay attention to it, primarily because of the limits of detection technologies.

Trim24 Limits the Ability of p53 to Function as a Tumor Suppressor

The tumor suppressor protein p53 has been nicknamed the “guardian of the genome” because it safeguards the DNA from long-term damage or stress by controlling the expression of numerous genes involved in DNA repair, cell division, and cell death.
