The double helix unwinds using helicase enzymes.
Helicase breaks the hydrogen bonds between base pairs to unzip the DNA. DNA polymerase then adds new complementary nucleotides to each original strand (semi-conservative replication). The other statements are incorrect (bases don't make sugars; polymerase builds new strands, not "putting the originals back together").
