Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.he pre-messenger RNA thus formed contains introns which are not required for protein synthesis. The pre-messenger RNA is chopped up to remove the introns and create messenger RNA (mRNA) in a process called RNA splicing. Transcription
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. 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. The pre-messenger RNA thus formed contains introns which are not required for protein synthesis. The pre-messenger RNA is chopped up to remove the introns and create messenger RNA (mRNA) in a process called RNA splicing (Figure 5). One strand of the DNA, the template strand (or noncoding strand), is used as a template for RNA synthesis. As transcription proceeds, RNA polymerase traverses the template strand and uses base pairing complementarity with the DNA template to create an RNA copy. 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. Proteins can be manufactured in large quantities because a single DNA sequence can be transcribed by many RNA polymerase molecules at once. 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-FROM DNA TO RNA This page takes a simple look at the structure of RNA and how the information in DNA is used to make messenger RNA. It is designed for 16 - 18 year old chemistry students, and if you are doing biology or biochemistry, you will probably need more detail than this page gives. Messenger RNA contains the information to make just one single polypeptide chain-in other words for just one protein, or even just a part of a protein if it is made up of more than one polypeptide chain. Overall structure. DNA has two strands arranged in a double helix. Transcription is the name given to the process where the information in a gene in a DNA strand is transferred to an RNA molecule. The coding strand and the template strand of DNA. The important thing to realise is that the genetic information is carried on only one of the two strands of the DNA. Messenger RNA contains the information to make just one single polypeptide chain-in other words for just one protein, or even just a part of a protein if it is made up of more than one polypeptide chain. Overall structure. DNA has two strands arranged in a double helix. DNA is double stranded. RNA is synthesized by RNA polymerase using the template strand. So the RNA has the same sequence of the coding strand, except that uracil is in the place of thymine. The process is called transcription, because both DNA and RNA are using the same language.  DNA to RNA Transcription. The DNA contains the master plan for the creation of the proteins and other molecules and systems of the cell, but the carrying out of the plan involves transfer of the relevant information to RNA in a process called transcription. The RNA to which the information is transcribed is messenger RNA (mRNA). The process associated with RNA polymerase is to unwind the DNA and build a strand of mRNA by placing on the growing mRNA molecule the base complementary to that on the template strand of the DNA. Transcription begins when an enzyme called RNA polymerase attaches to the DNA template strand and begins assembling a new chain of nucleotides to produce a complementary RNA strand. There are multiple types of types of RNA. In eukaryotes, there are multiple types of RNA polymerase which make the various types of RNA.
