DNA helicase is the main enzyme responsible for splitting the two strands of DNA (or 'unzipping' the DNA). This allows DNA polymerase to come along and copy the DNA, by joining free nucleotides (A, T, C, G) to the template strand of DNA. This is how a new strand of DNA is created.
info on DNA molecule "unzips" and the two strands unwind
because it reads the messages the DNA strand sends out and reads it over making sure its all right and there arent any mistakes so it can go into the cell
joining the nucleotides that form the new DNA strand
It's the REPLICATION.
DNA polymerase.
DNA Polymerase III is responsible for adding new nucleotides to the strand being synthesised. Also involved in DNA replication are DNA Polymerase I which replaces primers with nucleotides, and DNA Ligase which joins fragments of DNA together.
In humans, many enzymes are involved in DNA replication. Among them are: DNA polymerase I DNA polymerase III Ligase Primase Helicase DNA polymerase I and III perform the bulk of the actual reproduction--their job is to add nucleotides to the growing strands. The others perform specialized functions and are essential to the process.
DNA polymerase is the enzyme that replicates the pattern of the nucleotide bases. Its function is find the correct base, and then to bond it onto the original strand.

Helicase is the enzymes that splits the double helix into two separate strands, and DNA Polymerase (as opposed to RNA Polymerase) joins the nucleotides together in the new strands being created.
RNA polymerase is the enzyme that connect the new nucleotides together and proofreads them.

The polymerase itself does not separate the DNA strands. Helicase (another enzyme, sometimes found in complex with a polymerase holoenzyme) does the separating for it, ahead of the replication fork.

DNA first unwinds by the polymerase into two strands, then polymerases run over the two strands, replace a new strand on each old strand, forming two new DNA with one new strand and one original strand in each. (The polymerase is the enzyme)
