polymerase

 [pah-lim´er-ās]
an enzyme that catalyzes polymerization.
polymerase chain reaction a rapid technique for in vitro amplification of specific DNA or RNA sequences, allowing small quantities of short sequences to be analyzed without cloning.

pol·ym·er·ase

(pol-im'ĕr-ās),
General term for any enzyme catalyzing a polymerization, as of nucleotides to polynucleotides, thus belonging to EC class 2, the transferases.

polymerase

/po·lym·er·ase/ (pah-lim´er-ās) an enzyme that catalyzes polymerization.

polymerase

(pə-lĭm′ə-rās′, -rāz′, pŏl′ə-mə-)
n.
Any of various enzymes, such as DNA polymerase, RNA polymerase, or reverse transcriptase, that catalyze the formation of polynucleotides of DNA or RNA using an existing strand of DNA or RNA as a template.

polymerase

[pə·lim′ər·ās]
any enzyme that catalyzes polymerization, especially of nucleotides to polynucleotides.

POLA1

A gene on chromosome Xp22.1-p21.3 that encodes the catalytic subunit of DNA polymerase that plays a key role in initiating DNA replication.

pol·ym·er·ase

(pŏ-lim'ĕr-ās)
General term for any enzyme catalyzing a polymerization, as of nucleotides to polynucleotides, thus belonging to EC class 2, the transferases.

polymerase

Any enzyme that promotes the linkage of a number of similar or identical chemical subunits into repetitive long-chain molecules (polymers), especially of NUCLEOTIDES to form DNA or RNA. Derivation as in POLYMER with the -ase suffix denoting an enzyme.

polymerase

an enzyme that catalyses the joining of DNA or RNA nucleotides.

polymerase

an enzyme that catalyzes polymerization, particularly of nucleic acids.

RNA polymerase
1. an enzyme that synthesizes an RNA copy of the sequence in a limited region of DNA in a process known as DNA transcription. Called also DNA-dependent RNA polymerase.
2. a viral enzyme that synthesizes RNA from an RNA template during viral replication. Called also RNA-dependent RNA polymerase.
RNA-dependent RNA polymerase
see RNA polymerase (above).
Taq polymerase
a DNA polymerase that functions at high temperature; derived from the bacterium Thermus aquaticus and used in the polymerase chain reaction.

As an enzyme for PCR, we used the following types of DNA-dependent DNA polymerases: Taq DNA polymerase, Tersus DNA polymerase, Deep Vent DNA polymerase and Phusion DNA polymerase.
Both employ a pair of template-specific complementary primers to define the ends of the sequence to be amplified: these primers act to recruit and initiate polymerase function in making new product strands.
Polymerases were diluted in a buffer containing detergent and BSA.
Mullis, who was working at Cetus Corporation in Emeryville, California at the time invented the technique called the polymerase chain reaction (PCR).
More research is needed to clarify the biologic roles and the regulation of pol [Iota] and other TLS polymerases.
The method itself is simple and builds on the concepts of nucleic acid structure, strand denaturation and annealing, and DNA polymerase activity as covered in previous installments of this series.
The drugs that investigators tested target an RNA-snipping enzyme called an endonuclease that is a key subunit of the polymerase complex.

While enzymes of this class from different biological sources differ in terms of physical structure, capacity to catalyze side reactions, accuracy (fidelity) with which they work, and specific kinetic parameters, all DNA polymerases share the same core functional behavior in many key aspects.
Some polymerases repair short spans of damaged DNA, while others duplicate whole genomes at a time.
RNA polymerase Pol II is one out of three different RNA polymerases used by eukaryotic cells to produce the main categories of cellular RNA.
