During transcription, the RNA polymerase reads the template strand within a gene and adds complementary bases.
Transcription is the process by which the multi-unit enzyme RNA polymerase creates RNA molecules from a DNA template. Prior to translation, which is the process of decoding RNA into proteins, the transcription of genetic information into RNA is the initial stage in gene expression.
Together with transcription factors, RNAP forms a transcription pre-initiation complex by attaching to the promoter region on a DNA strand (PIC). The transcription procedure is started at this point. At the 5' end of a DNA strand, upstream, is the promoter site.
An intermediary enzyme called RNA polymerase is in charge of the process of transcription, in which DNA serves as a template for the synthesis of RNA-based genetic material. In the cell's nucleus, transcription occurs.
