This is a versatile RNA molecule. In his famous book, RNA acts as an intermediary, such as genetic information from DNA to protein synthesis machinery. RNA also plays a more active role, performing many functions of a catalyst and recognition usually reserved for proteins. Indeed, the majority of RNA in cells found in the ribosomes - protein synthesis, our cars - and transfer RNA molecules are used to add each new amino acids to the growing protein. In addition, many small RNA molecules involved in regulation, treatment and disposal of the continuous traffic of messenger RNA. RNA polymerase from a great responsibility to create all these different RNA molecules. RNA plant RNA polymerase is a large factory with many moving parts. Shown here since the entry 1i6h AP, is that the yeast cells. It consists of a dozen different proteins. Together, they form a team that surrounds the DNA strands, relaxes and builds a string of RNA from information contained in DNA. After starting enzyme, the rise of faith in DNA copy of RNA polymerase RNA chains of thousands of nucleotides long. Accuracy As expected, RNA polymerase must be an exact copy of genetic information. To improve accuracy, correctness is a simple step to facilitate the RNA chain. Active site has been created to be able to remove nucleotides and add them to the chain growth. The enzyme normally float around nucleotide mismatch to add more if necessary as time for enzyme to remove them. This process is somewhat useless if necessary nucleotides were also dropped from time to time, but this is a small price to pay for the creation of better RNA transcripts. In general, RNA polymerase makes a mistake while adding 10,000 nucleotides, or about once in RNA chain is created.
