RNA Polymerase
DNA polymerases. As an incoming nucleotide base-pairs with it's complement on the template strand, a DNA polymerase adds it to the end of the growing daughter strand (polymer).
DNA Polymerase
The polymerization of nucleotides occurs in nature by a process called replication. Generally, nucleotides don't self-assemble unless there is a template to assemble onto. So, during replication, the template strand is 'read' by the polymerase (an enzyme) and then it recruits and adds nucleotides onto the growing strand by forming bonds between the 5' carbon of one nucleotide and the 3' of the other.
Absolutely Yes, Life Depends Upon It. Nucleotides grouped in 3's are called ' triplet codons '. The four nucleotides, ATC&G, read as triplet codons, determine the order of amino-acids that are sequentially added to a nascent (growing) protein chain. See Proteins and Dna.
One major rule of DNA polymerase is that it can only synthesize DNA in the 5' to 3' direction. This means that it adds nucleotides to the growing DNA strand by linking the 3' end of the incoming nucleotide with the 5' phosphate group of the previous nucleotide. Another rule is that DNA polymerase requires a primer, a short segment of RNA or DNA, to initiate DNA synthesis. The primer provides a starting point for DNA polymerase to begin adding nucleotides.
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.

The 2 basic steps of polypeptide synthesis are:Transcription - the synthesis of mRNA from a DNA template. Only one strand of DNA is copied, and a single gene may be transcribed thousands of times.Translation - the process where ribosomes synthesize proteins using the mature mRNA transcript produced during transcription. The ribosome attaches to mRNA, and then moves along the mRNA adding amino acids to the growing polypeptide chain.
