RNA polymerase recognizes a specific base sequence in the DNA called a promoter and binds to it. The promoter identifies the start of a gene, which strand is to be copied, and the direction that it is to be copied.
RNA polymerase 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 ...
RNA polymerase (RNAP)
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.

RNA polymerases A class of enzymes that synthesize RNA molecules complementary to a DNA template.
The RNA polymerases
The RNA polymerases are huge multi-subunit protein complexes. Three kinds are found in eukaryotes.
rNA polymerase II, that transcribes all genes coding for polypeptides, recognises many thousands of promoters. most have the Goldberg Hogness or tATA box that is centred around position 25 and has the consensus sequence 5' TATAAAA 3'.
RNA polymerase I: transcribes genes encoding ribosomal RNA
RNA polymerase II: transcribes genes encoding messenger RNA and certain small nuclear RNAs
RNA polymerase III: transcribes genes encoding tRNAs and other small RNAs ...

RNA polymerase opens the part of the DNA to be transcribed. Only one strand of DNA (the template strand) is transcribed.
RNA polymerase I - makes the large ribosomal RNAs
RNA polymerase II - transcribes genes whose RNA's will be translated into proteins
RNA polymerase III - makes a variety of very small, stable RNAs including 5s ribosomal RNAs and transfer RNAs ...
RNA polymerase The enzyme responsible for forming mRNA during transcription.

(See Poly(A) polymerase, Polymerase chain reaction, RNA polymerase, Taq polymerase.) Polymorphisms. Variant forms of a particular gene that occur simultaneously in a population. Polynucleotide. A DNA polymer composed of multiple nucleotides.
This technique is based on the assumption that a highly-transcribed gene should have more molecules of RNA polymerase bound to it than will the same gene in a less-active state.
PromoterA short base sequence which is positioned close to the 5" end of a gene and acts as a recognition and binding site for the RNA polymerase complex prior to transcription of the gene.
RAPD Random amplification of polymorphic DNA.
The first step in production is for RNA polymerase to make RNA from a stretch of DNA. DNA can be thought of as a highway, with entrances and exits. The enzyme RNA polymerase is like a car.
Our aim is to alter substrate specificity in T7 RNA polymerase for efficient incorporation of dNTPs and other nucleotide analogs.
A convention used to describe features of a DNA sequence, gene or mRNA related to the position and direction (5' to 3') of transcription by RNA polymerase or translation by the ribosome.
RNA and ribosomal subunits must be constantly transferred from the nucleus where they are made to the cytoplasm, and histones, gene regulatory proteins, DNA and RNA polymerases, ...
Downstream: The direction which RNA polymerase moves during transcription (5' to 3') and ribosomes moves during translation.
A regulatory region a short distance upstream from the 5' end of a transcription start site that acts as the binding site for RNA polymerase. A region of DNA to which RNA polymerase binds in order to initiate transcription.
