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 ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

Every time a cell divides, it must accurately copy its entire genetic instruction manual. Before this process can begin, cells load their DNA-copying motor—a complex of six subunits known as the ...

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 ...

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 ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides, which happens constantly. Without this process, we would die.

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 ...

TBX5 gene loss disrupts 3D DNA folding, impacting heart cell gene regulation Loss of one TBX5 copy causes variable heart defects by altering genome structure TBX5 directs cohesin to form chromatin ...
