An enzyme that catalyzes the synthesis of ribonucleotides into a sequence complementary to a pre-existent DNA template.
the enzyme that moves along the DNA strand, reads the nucleotides one by one, and synthesizes a complementary mRNA molecule according to the principle of complementary base pairing.
an enzyme which helps synthesize mRNA by transcribing the nucleotide sequence in DNA.
an enzyme used to create mRNA from either a strand of DNA or RNA.
An enzyme that catalyzes the synthesis of ribonucleic acid (RNA) by using deoxyribonucleic acid (DNA) as a template.
any of the enzyme complexes directly responsible for transcription -- the manufacture of RNA from the 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).
An enzyme responsible for the synthesis of RNA from its constituent ribonucleotides (NTPs), using one strand of DNA as template.
The enzyme that catalyses the synthesis of a complementary strand of RNA from either a DNA strand or an RNA strand in some viruses.
An enzyme that makes RNA.
RNA poe-Lim-er-ase An enzyme that takes part in DNA replication and RNA transcription. 317, 327
An enzyme complex that polymerizes RNA from ribonucleotides (NTPs), using one strand of DNA as template (hence called "DNA-dependent RNA polymerase). The core RNAP from E. coli is composed of five subunits: 2 alpha subunits, beta, beta', and omega. Upon binding another subunit called sigma, RNAP is called a holoenzyme. The sigma subunit (or sigma factor) reduces the nonspecific affinity of RNAP for DNA and increases the specific binding to certain promoter sequences. A variety of different sigma subunits exist, each promoting RNAP binding to different promoters under specific physiological conditions.
Enzymatic activity responsible for DNA-dependent synthesis of RNA. In prokaryotes there is only one RNA polymerase. In eukaryotes, there are three, each of which transcribes a different group of genes.
an enzyme that catalyzes the synthesis of RNA; the polymerase moves along the DNA temple strand, growing its chain of RNA in the 5'-to-3' direction one ribonucleotide at a time.
An enzyme that catalyses the synthesis of nucleic acids on preexisting nucleic acid templates, assembling RNA from ribonucleotides.
During transcription, an enzyme that attaches to the promoter region of the DNA template, joins nucleotides to form the synthesized strand of RNA and detaches from the template when it reaches the terminator region. PICTURE
An enzyme that catalyses the synthesis of RNA from a DNA template. See polymerase; RNA.
the enzyme that unzips DNA and make a complimentary RNA strand.
The enzyme that polymerizes ribonucleotides.
an enzyme that transcribes an RNA molecule from the antisense strand of a DNA molecule
An enzyme that catalyzes the synthesis of RNA from a DNA template. RNA polymerase is one part of the complex set of mechanisms that translate a gene onto its product.
An enzyme that catalyzes the synthesis of an RNA strand from a DNA template. In eukaryotes, there are several classes of RNA polymerase. Structural genes for proteins are transcribed by RNA polymerase II.
an enzyme that links the growing chain of ribonucleotides during transcription.
An enzyme that copies one strand of DNA or RNA (the template strand) to make the complementary RNA strand using as substrates ribonucleoside triphosphates.
RNA polymerase (RNAP or RNApol) is an enzyme responsible for making RNA from a DNA or a RNA template. In all cells RNAP is needed for constructing RNA chains from a DNA template, a process termed transcription. In scientific terms, RNAP is a nucleotidyl transferase that polymerizes ribonucleotides at the 3' end of an RNA transcript.
