In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and collaborators have uncovered one of the earliest steps in DNA replication: the moment a cell first opens its DNA to begin making a copy ...

Congenital heart disease is the most common birth defect, affecting approximately 1 in 100 babies born each year. One of the many causes of this disorder is having only one functional copy of the gene ...

Computational chemists at the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences have developed a comprehensive software suite to create accurate models of DNA in biomolecular ...

A baby can inherit one healthy copy of TBX5 and still develop serious heart defects if the other copy does not work. That genetic imbalance is one cause of congenital heart disease, the most common ...

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying "mistakes" account for nearly two-thirds of the mutations that ...

The findings, published in Science Advances, reveal a previously unrecognized mechanism to protect DNA replication and genome stability that could lead to new treatments for some cancers. "This study ...
