DNA News and Research

RSS

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).

Cancer researchers seek safe reduction of radiotherapy

Around half of patients receive radiotherapy as part of their cancer treatment but the dose is limited by the possibility of causing side effects (toxicity) to the normal tissues and organs that surround the tumour.

Residual fetal cells in women may provide protection against breast cancer

Fetal cells that persist in a woman's body long after pregnancy - a common occurrence known in scientific circles as fetal microchimerism - in some cases may reduce the woman's risk of breast cancer, according to researchers at Fred Hutchinson Cancer Research Center.

Worm study sheds light on how the human body ages

Microscopic worms used for scientific research are living longer despite cellular defects, a discovery that is shedding light on how the human body ages and how doctors could one day limit or reverse genetic mutations that cause inherited diseases, according to a new University of Colorado at Boulder study.

New view of what causes greatest genetic variability among individuals

A study by Yale researchers offers a new view of what causes the greatest genetic variability among individuals - suggesting that it is due less to single point mutations than to the presence of structural changes that cause extended segments of the human genome to be missing, rearranged, or present in extra copies.
