Rna polymerase (RNAP or RNApol) is an enzyme that is responsible for making rna from a dna template. It is an enzyme that is responsible for making rna from a dna template.
An enzyme that catalyzes the synthesis of an RNA strand from a DNA template. The enzyme that polymerizes RNA by using DNA as a template. It can also act as a primase initiating DNA replication. (Also known as transcriptase or RNA transcriptase).  Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis. Since primase produces RNA molecules, the enzyme is a type of RNA polymerase. Primase functions by synthesizing short RNA sequences that are complementary to a single-stranded piece of DNA, which serves as its template. 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. This complex initiates transcription, and the RNA polymerase begins mRNA synthesis by matching complementary bases to the original DNA strand. The mRNA molecule is elongated and, once the strand is completely synthesized, transcription is terminated. 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. This complex initiates transcription, and the RNA polymerase begins mRNA synthesis by matching complementary bases to the original DNA strand. The mRNA molecule is elongated and, once the strand is completely synthesized, transcription is terminated. 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. 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. Both RNA and DNA are nucleic acids, which use base pairs of nucleotides as a complementary language. n. A polymerase that catalyzes the synthesis of a complementary strand of RNA from a DNA template, or, in some viruses, from an RNA template. Other factors ... RNA polymerase During transcription, an enzyme that attaches to the promoter region of the DNA template, joins nucleotide s to form the synthesized strand of RNA and detaches from the template when it reaches the terminator region. PICTURE ...  RNA is transcribed in the nucleus; processed, it is transported to the cytoplasm and translated by the ribosome. At the end of its life, the mRNA is degraded. In transcription, the codons of a gene are copied into messenger RNA by RNA polymerase.In simple word or formation of RNA from DNA is known as transcription. This RNA copy is then decoded by a ribosome that reads the RNA sequence by base-pairing the messenger RNA to transfer RNA, which carries amino acids.  Compare RNA-dependent RNA polymerase. RNA polymerase (RNAP or RNApol), also known as DNA-dependent RNA polymerase, is an enzyme that produces primary transcript RNA. In cells, RNAP is necessary for constructing RNA chains using DNA genes as templates, a process called transcription.  RNA polymerase. Rna polymerase (RNAP or RNApol) is an enzyme that is responsible for making rna from a dna template. In all cells RNAP is needed for constructing rna chains from a dna template, a process termed transcription. Rna polymerase enzymes are essential and are found in all organisms, cells, and many viruses.
