The document describes the process of transcription in a cell nucleus. DNA in the chromatin contains the genetic code for amino acids. RNA polymerase reads the DNA code in the promoter region, then synthesizes a complementary mRNA strand in the coding region until reaching the termination sequence. The mRNA strand passes through the nuclear pore into the cell.
