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).

Advancements in use of zinc finger nucleases to produce genetically modified pigs

Sangamo BioSciences, Inc. announced the publication of a study demonstrating the use of zinc finger nucleases (ZFNs) to produce genetically modified pigs. The study, which was published in the Proceedings of the National Academy of Sciences (PNAS), represents a significant advancement in the development of improved, less immunogenic animal tissue as a source for transplant into humans.

UCSF, Kaiser Permanente achieve first major milestone in genomics project

One of the nation's largest and most diverse genomics projects has reached its first major milestone in just 15 months. Scientists have genotyped the DNA and analyzed the length of chromosome tips in more than 100,000 Kaiser Permanente members who agreed to be part of the research.

Scientists discover new bases of DNA

For decades, scientists have known that DNA consists of four basic units -- adenine, guanine, thymine and cytosine. Those four bases have been taught in science textbooks and have formed the basis of the growing knowledge regarding how genes code for life.

First genome-wide mapping of DNA modification in embryonic stem cells

Stem cell researchers at UCLA have generated the first genome-wide mapping of a DNA modification called 5-hydroxymethylcytosine (5hmC) in embryonic stem cells, and discovered that it is predominantly found in genes that are turned on, or active.

Key finding sheds new light on common bleeding disorders

A simple cut to the skin unleashes a complex cascade of chemistry to stem the flow of blood. Now, scientists at Washington University School of Medicine in St. Louis have used evolutionary clues to reveal how a key clotting protein assembles. The finding sheds new light on common bleeding disorders.

Falling may be an early sign of Alzheimer's

In a new study presented at the Alzheimer's Association's annual International Conference in Paris it was reported that older people whose brain scans showed signs of amyloid plaques - an early indicator of Alzheimer's disease - but who were otherwise healthy, had twice the risk of falls as people without brain amyloid.

Alzheimer’s risk transmitted from mother to offspring: Study report

According to preliminary research adults whose mothers develop late-onset Alzheimer's disease may have an increased risk for the disease, compared with children of dads with late-onset Alzheimer's. The findings were presented at the Alzheimer's Association International Conference 2011.
