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).

Multiresolution DNA Simulation in Viral Genome Packaging

Researchers at the University of Illinois Urbana-Champaign stated in the journal Nature that a computational model of the more than 26 million atoms in a DNA-packed viral capsid broadens the knowledge of virus structure and DNA dynamics, discoveries that potentially open up new research directions and therapeutic targets.

'lncREST' RNA Unveiled as Key Player in DNA Replication Stress Response

Researchers at Cima Universidad de Navarra have discovered that a ribonucleic acid that does not contain information to make proteins (long non-coding RNA) plays a crucial role in signalling and repairing errors in DNA replication during cell division.

Researchers Identify Proteins to Reprogram Fibroblasts into Limb Progenitor Cells

In a collaborative study, researchers from Kyushu University and Harvard Medical School have identified proteins that can turn or "reprogram" fibroblasts -; the most commonly found cells in skin and connective tissue -; into cells with similar properties to limb progenitor cells.

Evolutionary Mystery Identified in Genome of Plants

Cold Spring Harbor Laboratory (CSHL) has enabled the significant advancement of plant genomics through its involvement in sequencing the first plant genome. Now, the same research laboratory hopes to address why introducing the same mutation in different crops does not always result in the desired traits.
