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).

One reason behind frequent miscarriages could be faulty sperms

Scientists at the Imperial College in London have found that one of the reasons behind frequent miscarriages in a woman could be the fault of the sperms of their partners. Recurrent miscarriages are defined as three or more miscarriages that occur before 20 weeks of pregnancy are completed. One in 50 couples in the UK are affected by recurrent miscarriages.

Research illuminates abilities of ADAR1 to ‘hyper-mutate’ tumor suppressor RNAs in leukemia

Writing in the January 3 issue of Cancer Cell, researchers at University of California San Diego School of Medicine report that detection of "copy editing" by a stem cell enzyme called ADAR1, which is active in more than 20 tumor types, may provide a kind of molecular radar for early detection of malignancies and represent a new therapeutic target for preventing cancer cell resistance to chemotherapy and radiation.

Bulldogs' screw tails linked to rare inherited syndrome in humans

With their small size, stubby faces and wide-set eyes, bulldogs, French bulldogs and Boston terriers are among the most popular of domestic dog breeds. Now researchers at the University of California, Davis, School of Veterinary Medicine have found the genetic basis for these dogs' appearance, and linked it to a rare inherited syndrome in humans.

Researchers reveal cause of possible genetic problems in mitochondria

A group of researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine has revealed the importance of eliminating any excess of defective products that might have accumulated in the mitochondria, as its presence generates mitochondrial instability and information loss on the mitochondrial genome.

Study provides new insights into how genes are activated

In a study in Nature, researchers at Karolinska Institutet present a new method for analyzing how instructions in the genome control how our genes are activated in individual cells.

Rockefeller scientists uncover genetic mutation responsible for tuberculosis vulnerability

If you live in the United States, you are unlikely to come into contact with the microbe that causes tuberculosis. Your odds of encountering the microbe are so low, in fact, that risk factors for the disease can easily go unnoticed: If you happened to carry a gene that predisposed you to tuberculosis, you likely wouldn't know.

Himalayan marmot genome offers clues to high-altitude adaptation

Himalayan marmots can survive at altitudes up to 5,000 meters in the Himalayan regions of India, Nepal, and Pakistan and on the Qinghai-Tibetan Plateau of China, where many of them face extreme cold, little oxygen, and few other resources.

Genetic testing can help personalize diagnosis and treatment of kidney disease, study shows

A new study has found that genes cause about 1 in 10 cases of chronic kidney disease in adults, and identifying the responsible gene has a direct impact on treatment for most of these patients.

Researchers identify hundreds of new genes linked to blindness in lab mice

Hundreds of new genes linked to blindness and other vision disorders have been identified in a screen of mouse strains. Many of these genes are likely important in human vision and the results could help identify new causes of hereditary blindness in patients.

Enhancers can be predicted through ChIP-seq technology

In genetics, an enhancer is a short region of DNA that can be bound by proteins to increase the likelihood that transcription of a particular gene will occur.
