Here we can distinguish the following phases:
a) Initiation: the RNA polymerase binds to a cofactor that allows binding to a region of DNA called the promoter, which has a secuenciaa TATAAT or TTGACA.
b) Elongation: RNA polymerase traverses the DNA strand at its 5 'synthesizing a strand of mRNA 5'-3'
c) Completion: has two variants. Cofactor involved in a "p" and another said cofactor is not involved. The process ends when you reach a sequence rich in G and C (area called the operator). The DNA returns to normal and the mRNA is free.
d) Maturation: if what is there is a mature mRNA, but is there a tRNA or rRNA splicing processes.
