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 ...

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

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 ...
