When DNA replication takes place weaker hydrogen bonds that join complementary bonds together become broken. The two different sides of the DNA ladder start to unravel. The parent strands, however, stay joined. The parent strands that remain become molds to nucleotides, that attach themselves to complementary bases. Polymerases fuse those free nucleotides into the DNA strand.
Step 1: A special enzyme (helicase) "unzips" the double helix that is the DNA and Single Strand Binding Proteins stabilise the structure.
Step 2: A primer with a short DNA sequence complementary to a region on the parental strand is added by a primase to allow replication to occur.
Step 3: Another enzyme (DNA polymerase) combines free-floating deoxyribonucleosides triphosphate to their corresponding nucleotides that are attached to the DNA strand, attaching the free nucleotide to the 3' OH tail of the previous section, forming a complementary strand of DNA from the 5' to 3' direction.
Really it's that easy. When it's finished, there are two identical strands of DNA, assuming no mutations occured.

DNA replication takes place when?
DNA replication takes place when preceding interphase.
Which enzyme would probably not be needed for DNA replication?
DNA helicase
What is copied before mitosis begins?
DNA, the genetic material, of course. Also mitochondria and chloroplasts need to divide. This is the process of mitosis where two daughter cells are produced and both will need the complete complement of genetic material; DNA.
Some organisms use single-stranded rather than double-stranded DNA In these organisms which enzyme would probably not be needed for DNA replication?
DNA helicase
The process of what produces a new copy of an organism's genetic information?
The process that makes a new copy of an organism's genetic information and then passes it on to new cells is called mitosis.
Where does DNA replication takes place?
DNA replication takes place in NUCLEUS
Where the cell does DNA replication take place?
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
In which phase does chromosome replication occur?
Chromosomal replication and DNA replication takes place in S-phase.
Where does replication of the two DNA strands takes place?
in a direction opposite to that of the replication fork
Replication of the two DNA strands takes place?
In the same directions of the replication fork
Where in the cell does DNA take place?
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
What phase does the DNA synthesis occurs?
replication of DNA takes place during the interphase
Where does replication in DNA take place?
DNA replication takes place in the nucleus of a eukaryotic cell (plant or animal cell or the cytoplasm of a prokaryotic cell (bacteria).
What takes place in the nuleus before cell division?
DNA Replication :)
Where does DNA replicate take place in the cell?
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
Does DNA replication take place in the cytoplasm of eukaryotic cells?
No, DNA replication takes place inside the nucleus during S phase of cell cycle.
What is the process called when DNA synthesis takes place during interphase?
Replication is when DNA makes more DNA
