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).

Residual fetal cells in women both detrimental and beneficial to women's health

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.

London School of Hygiene to play key role in global collaboration on adverse drug reactions

The London School of Hygiene & Tropical Medicine is to be a key player in the first global research collaboration aimed at identifying the genetic markers related to Adverse Drug Reactions (ADRs).

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.

Genetic sequence of Giardia complete

Giardia lamblia, one of the most common human parasites in the United States, causes more than 20,000 intestinal infections a year, often through contact with contaminated drinking or swimming water.

Genetic test announced for suicidal ideation in patients using antidepressant drugs

NeuroMark, a Boulder, Colorado company, announced today the immediate availability of a genetic test to identify people at risk of suicidal ideation - thoughts of committing suicide - when prescribed an antidepressant drug.

Smallpox evolved earlier than believed

Smallpox is older than thought, according to results of a new technique reported in the Sept. 24 issue of the Proceedings of the National Academy of Sciences by researchers from Lawrence Livermore National Laboratory and the Centers for Disease Control (CDC).

The jury is in: microRNAs can cause tumors to metastasize

These tiny molecules fine-tune protein production and play a powerful role in biological processes ranging from development to aging. Now scientists have proved that they can prompt otherwise sedentary cancer cells to move and invade other tissues.

Transposons could make for safer gene delivery system

To move a gene from point A to point B, scientists and gene therapists have two proven options: a virus, which can effectively ferry genes of interest into cells, and a plasmid, an engineered loop of DNA that can do the same thing, albeit usually only on a short-term basis.
