The Double Helix
helicase
When double stranded DNA is unwound into single stranded DNA, single-strand binding proteins bind to each single stranded DNA strand and prevent the two strands from reattaching to each other, allowing DNA replication to continue.

The Double Helix
helicase
During DNA replication, DNA polymerase binds free DNA nucleotides to an unzipped DNA strand. During transcription, RNA polymerase binds free RNA nucleotides to the unzipped anti-sense DNA strand.

One
DNA polymerase attaches (polymerizes) nucleotides together to make polynucleotides using a strand of DNA that has already been unzipped by DNA helicase.
A strand of DNA can be "unzipped" on its own or by human intervention to replicate. This process does not harm the DNA and provides a carbon copy of itself.
