Another enzyme then moves along the exposed DNA strand joining newly arrived nucleotides into a new DNA strand that is complementary to the template. DNA polymerase is represented by the small brown pastebrush in the animation.

DNA polymerase makes very few errors and it corrects most of those quickly. In addition, there are other enzymes that follow along and "proofread" the nucleotides to be certain that the new nucleotides are actually complementary to the template strand. Any misfits are booted out and replaced with the proper base. Thanks to this magnificent system,
Each cell contains a family of more than thirty enzymes necessary to insure the accurate replication of DNA.

Not represented in the animation are the primers necessary for DNA replication. Though DNA polymerase can elongate a polynucleotide strand by adding new nucleotides, it cannot start a strand from scratch because it can only bond new nucleotides to a free sugar (3') end of a nucleotide chain. This small strand of nucleotides (binds) by complementary base pairing to the beginning of the area being copied. With the primer in place, DNA polymerase is then able to continue adding the rest of the pairs of the segment until a new double strand of DNA is completed. Primers are formed from free nucleotides in the cell by enzymes called .

The process of protein synthesis translates the codons (nucleotide triplets) of the messenger RNA (mRNA.
For instance, bacteria contain a single type of RNA polymerase, while eukaryotes Protein Interaction, and Cell Differentiation.

(As a result of this bonding, the DNA assumes its helical shape.) Therefore, the two strands of DNA are said to be complementary.

This little animation in the upper left provides a nice overview of the process of DNA replication. However, it does not approach representing the complexity of DNA replication. I strongly recommend watching the attached videos if you are preparing for an exam in an advanced high school or college class. Thank you to Steven Kuensting for sharing his work on Wikimedia Commons.

You will use a protein called Reverse Transcriptase, which is a polymerase that synthesizes DNA from RNA.

Then DNA polymerase synthesizes complementary strands

Before a cell divides, its DNA must be (duplicated). The two strands of a DNA molecule are separated and each is used as a pattern or to produce a complementary strand. Each template and its new complement together then form a new DNA double helix, identical to the original. Because the two new DNA molecules each contain a new strand of nucleotides along with one strand from the parent molecule, we say that the process of DNA replication is .

Before replication can occur, the length of the DNA double helix about to be copied must be . Once the DNA strands have been unwound, they must be to expose the bases so that new nucleotide partners can bond to them. These tasks are accomplished by the enzyme—one of many proteins that work as a micro-tools inside the cell. In the animation to the left, helicase is represented by the small key to symbolize unlocking the molecule.
