Transcription begins with a bundle of factors assembling at the promoter sequence on the DNA in red.

Decades of research have resulted in a remarkably detailed understanding of the molecular mechanisms of bacterial DNA replication, transcription and translation. Our understanding of the kinetics and physical mechanisms that drive these processes forward has been expanded by the ability of single-molecule in vitro techniques, such as force spectroscopy and single-molecule Forster fluorescence resonance energy transfer smFRET , to capture short-lived intermediate states in complex pathways. Furthermore, these technologies have revealed novel mechanisms that support enzyme processivity and govern the assembly of large multicomponent complexes.

The promoter is a region on the DNA, which is located upstream, near the transcription start side. Transcription is initiated. The poly A tail stabilizes the mRNA from degradation in the cytoplasm. The poly A tail also helps to transport the mRNA from the nucleus to the cytoplasm.

If the gene encodes a protein , the transcription produces messenger RNA mRNA ; the mRNA, in turn, serves as a template for the protein's synthesis through translation. This is because the positive-sense strand contains the information needed to translate the viral proteins for viral replication afterwards. This process is catalyzed by a viral RNA replicase. A DNA transcription unit encoding for a protein may contain both a coding sequence , which will be translated into the protein, and regulatory sequences , which direct and regulate the synthesis of that protein. The regulatory sequence before " upstream " from the coding sequence is called the five prime untranslated region 5'UTR ; the sequence after " downstream " from the coding sequence is called the three prime untranslated region 3'UTR. Only one of the two DNA strands serve as a template for transcription.

LECTURE NOTES on DNA REPLICATION and PROTEIN SYNTHESIS: Transcription and Translation DNA Structure

In both prokaryotes and eukaryotes, the second function of DNA the first was replication is to provide the information needed to construct the proteins necessary so that the cell can perform all of its functions. The mRNA then provides the code to form a protein by a process called translation. Through the processes of transcription and translation, a protein is built with a specific sequence of amino acids that was originally encoded in the DNA. This module discusses the details of transcription. The flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma [link] , which states that genes specify the sequences of mRNAs, which in turn specify the sequences of proteins.
