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 method could more sensitively detect circulating tumor cells

Somatic mutation acts as natural gene therapy in patients with GATA2 deficiency

Researchers affiliated with the Center for Cell-Based Therapy (CTC) in Ribeirão Preto, Brazil, have identified for the first time a non-hereditary mutation in blood cells from a patient with GATA2 deficiency, a rare autosomal disease caused by inherited mutations in the gene that encodes GATA-binding protein 2 (GATA2).

Scientists expand Darwin's evolutionary theory to include "molecular Darwinism"

Darwin's theory of evolution should be expanded to include consideration of a DNA stability "energy code" - so-called "molecular Darwinism" - to further account for the long-term survival of species' characteristics on Earth, according to Rutgers scientists.
