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).

Novel DNA-based nanogel for targeted delivery of chemotherapeutics

Current chemotherapy regimens slow cancer progression and save lives, but these powerful drugs affect both healthy and cancerous 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.

New data can aid research on disease mutations, preserve endangered species

A large international consortium led by scientists at Uppsala University and the Broad Institute of MIT and Harvard has sequenced the genome of 130 mammals and analyzed the data together with 110 existing genomes to allow scientist to identify which are the important positions in the DNA.
