Transcription is the process by which the information in DNA is copied into messenger RNA (mRNA) for protein production.
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene. In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation. Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template. Transcription factors can bind to specific DNA sequences called enhancer and promoter sequences in order to recruit RNA polymerase to an appropriate transcription site. Together, the transcription factors and RNA polymerase form a complex called the transcription initiation complex. Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. Transcription factors can bind to specific DNA sequences called enhancer and promoter sequences in order to recruit RNA polymerase to an appropriate transcription site. Together, the transcription factors and RNA polymerase form a complex called the transcription initiation complex. During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript. Transcription proceeds in the following general steps: 1  One or more sigma factor protein binds to the RNA polymerase holoenzyme, allowing it to bind to promoter DNA. 1 RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix. 2  This is done by breaking the hydrogen bonds between complementary DNA nucleotides. 3  RNA polymerase adds matching RNA nucleotides to the complementary nucleotides of one DNA strand. Transcription is the synthesis of RNA from a DNA template where the code in the DNA is converted into a complementary RNA code. Translation is the synthesis of a protein from an mRNA template where the code in the mRNA is converted into an amino acid sequence in a protein.  Transcription & Translation: Transcription (Basic). Transcription is the process by which the information in DNA is copied into messenger RNA (mRNA) for protein production. Transcription begins with a bundle of factors assembling at the promoter sequence on the DNA (in red). Here, two transcription factors are already bound to the promoter.  1 Elongation. 2  Certain proteins called transcription factors unwind the DNA strand and allow RNA polymerase to transcribe only a single strand of DNA into a single stranded RNA polymer called messenger RNA (mRNA). 3  The strand that serves as the template is called the antisense strand. DNA Transcription. 1  RNA Polymerase Binds to DNA. 2  DNA is transcribed by an enzyme called RNA polymerase. 3  Specific nucleotide sequences tell RNA polymerase where to begin and where to end. 4  RNA polymerase attaches to the DNA at a specific area called the promoter region. 5  Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.  DNA transcription is a process that involves transcribing genetic information from DNA to RNA. The transcribed DNA message, or RNA transcript, is used to produce proteins. DNA is housed within the nucleus of our cells. It controls cellular activity by coding for the production of proteins.

Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (mRNA) by the enzyme RNA polymerase. 1 RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix. 2  This is done by breaking the hydrogen bonds between complementary DNA nucleotides. 3  RNA polymerase adds matching RNA nucleotides to the complementary nucleotides of one DNA strand.
