5.9 Transcription

. Transcription Francis Crick proposed the Central dogma of protein synthesis in molecular biology states that genetic information flows as follows: The process of copying genetic information from one strand of DNA into RNA is termed transcription . This process takes place in presence of DNA dependent RNA polymerase. In some retroviruses that contain RNA as the genetic material (e.g, HIV), the flow Molecular Genetics to form the transcription bubble. The core enzyme moves ahead, manufacturing RNA leaving the sigma subunit behind at the promoter region. The end of a gene is marked by a terminator sequence that forms a hair pin structure in the RNA. The sub-class of terminators require a recognition protein, known as rho (ρ), to function.
