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).

New research may upend long-held scientific dogma about short telomeres and cancer risk

Johns Hopkins Medicine scientists say their 20-year study of more than 200 people with premature aging syndromes caused by abnormally short telomeres, or shortened repetitive DNA sequences at the ends of chromosomes, may upend long-held scientific dogma and settle conflicting studies about how and whether short telomeres contribute to cancer risk.

SARS-CoV-2 infection disrupts the RNA modifications, study reports

Coronavirus disease (COVID-19) hijacks parts of infected cells' vital RNA machinery, thereby blocking important functions in the cells. These damaging changes in the RNA can likely be reversed, potentially leading to new drugs against COVID-19, University of Gothenburg researchers show.

Beethoven's cause of death revealed through DNA analysis of his hair

In a recent article published in the journal Current Biology, an international team of researchers sequenced the whole genome to high coverage from eight authenticated hair strands from Ludwig van Beethoven, one of the most influential European classical music composers born in 1770. He died on March 27, 1827.
