Protein Machinery Replicates DNA

Caption

Protein machinery involved in DNA replication caught in action: The "origin recognition complex" (yellow), already activated by an initiation factor (brown), grabs onto the helicase core (purple blue) to load the helicase ring onto the DNA double helix (red). The background is a cryo-electron micrograph of many of these complexes (dark) frozen in ice.
