What is a copy bubble and what is involved in copying DNA?

Our cellular DNA replicates from an internal point called the origin of replication.

Double-stranded DNA (DSDNA) is partially broken down or reduced by DNA helixes to form a duplicate bubble.

Inside these bubbles, replication complexes form (they can be seen as yellow balls in the image below) and DNA replicates in both directions, dividing the replica.
