First place decomposition of hydrogen weak ties, related with the bases pairs in place initiator, who is elected by the enzyme topoisomerase which opens the double spiral of DNA. Then the RNA polymerase is the enzyme that builds polymers, pull polynucleotide complementary RNA to fonnuar a short RNA, the RNA called primary (primary), which developed in the initial part of each segment of DNA ready for replication. RNA makes it more attractive primary DNA polymerase official, which enables the approach of nucleotides of DNA (to extend the primary) with the bases exposed coil complementary template (original template). New DNA is enhanced by hydrogen connections between complementary bases. DNA polymerase extension allows arrays of DNA complementary to the primary RNA and forms a new half-helix. The polymerase reads passing and away basis attached incorrectly (inadequate) and assures them konigjohen with complementary bases (appropriate) ie, it sets new nucleotide position (tail or edge) 3 'sugar in that spiral to is increasing. Special polymerase RNA (primaza) as the primary synthesizes, destroyed by nucleases exon DNA polymerase (deoksiribonukleaza or dNTPs). The primary typical consists of 18 nucleotides in length -28, so all strings of DNA, begin to form part of a small RNA (primary care), which is synthesized by RNA polymerase-specific, with the ability to initiate verse, but unable to konigjon sequencing errors in primary care base. These errors must be corrected with and replaced with varying degrees of replication. The primary RNA, the enzyme leave and replaced with corrected bases of DNA.
