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).

Choosing alternate pathways of DNA repair to limit harmful chromosomal rearrangements

Homologous recombination is an essential process of DNA repair to maintain genomic integrity of the organism.

MSC‐induced Treg population can yield abundant replacement for naturally occurring T-cells

A new study released today in STEM CELLS suggests for the first time that regulatory T-cells (Treg) induced by mesenchymal stromal cells can yield an abundant replacement for naturally occurring T-cells, which are vital in protecting the body from infection.

Understanding evolution of early life may be trickier than previously thought

Biologists have long hoped to understand the nature of the earliest living organisms on Earth. If they could, they might then be able to say something about how, when, and where life arose on Earth, and perhaps by extension, whether life is common in the Universe.

DNA may not be the 'blueprint' for life, just a scrambled list of ingredients

The common view of heredity is that all information passed down from one generation to the next is stored in an organism's DNA. But Antony Jose, associate professor of cell biology and molecular genetics at the University of Maryland, disagrees.
