A team has published pictures at very high atomic resolution of the multi-part protein complex that performs the very first step in the incredibly complex genome-replication dance that occurs when one ...

Unlike nuclear DNA, mitochondrial DNA (mtDNA) is circular in nature and organized as mitochondrial nucleoids comprised of DNA-protein complexes that are distributed in the matrix. It is also inherited ...

Genome duplication must occur before cell division, so that both progeny cells inherit a complete copy of the genetic material. DNA replication is initiated at particular chromosomal sites called ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...
