At school, it's often presented as a tidy double helix but scientists are revealing the varied and intricate shapes of DNA molecules.

DNA doesn’t knot under stress. A new study finds it coils into plectonemes, reshaping models of genome mechanics. For decades ...

DNA repair enzymes, such as the ligase shown here that joins broken DNA strands, scan replicating DNA in the nucleus. Particularly difficult cases are now known to be transported to the inner edge ...

A new study has found that ORC plays a broad, unexpected role in regulating human cell gene expression and chromatin ...

A new Northwestern Medicine study has revealed how a common inherited mutation disrupts red blood cell development and sparks ...

The precision of DNA replication is not merely a matter of chance; it’s a well-coordinated dance between various proteins and enzymes.

Biochemistry: Structure and function of biological macromolecules; Enzymes – basic mechanisms of enzyme ... Molecular Biology: Landmark experiments that established DNA is the genetic material; DNA ...

This study provides valuable insights into microtubule remodeling during liver-stage Plasmodium berghei development, demonstrating that deletion of the alpha-tubulin C-terminal tail impairs parasite ...

"They’ve been called selfish DNA,” Holt explains. “They replicate themselves and expand their number over ... in HIV may also ...

Postmitotic myotubes cannot complete DNA replication following forced cell cycle reactivation. Comparative genomic ...
