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.
