In bacteria, to start DNA replication, two replisomes attach to the DNA at a set origin point and head in opposite directions along the loop of DNA, copying DNA until they meet on the other side.

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes ...

Postmitotic myotubes cannot complete DNA replication following forced cell cycle reactivation. Comparative genomic hybridization and Xenopus egg extracts show that this is primarily due to a diffuse ...

Caption In the DNA fiber assay used in this study, cells labeled with IdU (green) and CldU (red) nucleotide analogs were sorted into substages of S phase before being subjected to the DNA fiber ...

Scientists have created an unprecedented 3-dimensional structural model of a key molecular "machine" known as the BAF complex, which modifies DNA architecture and is frequently mutated in cancer ...

AI analyzes, predicts protein - DNA structures DeepPBS employs a geometric deep learning model, a type of machine-learning approach that analyzes data using geometric structures.
