Check THREE that apply. What happens during DNA replication?

The DNA is tightened up to condense its material.

The strand of DNA is "unzipped" by an enzyme down the middle of the rungs.

The process is finished when all sugars, bases and phosphates have found their way to join their match.

Each side rebuilds itself by taking free-floating chemicals found in the nucleus and using them to fill in the missing pieces.

When the material of the DNA is condensed, it undergoes a mini -explosion that sends out copies of DNA throughout new cells.
