primer


Also found in: Dictionary, Thesaurus, Financial, Acronyms, Encyclopedia, Wikipedia.

prim·er

(prī'mĕr),
1. A molecule, which may be a small polymer, that initiates the synthesis of a larger structure. Synonym(s): starter
2. A pheromone that causes a long-term physiologic change.

primer

(prī′mər)
n.
Genetics A segment of DNA or RNA that is complementary to a given DNA sequence and that is needed to initiate replication by DNA polymerase.

primer

1. A short RNA sequence paired with one DNA strand that provides a free 3’-OH end on which synthesis of a deoxyribonycleotide chain can start.
2. The short nucleotide sequence used to start the POLYMERASE CHAIN REACTION (PCR) process.

primer

a short OLIGONUCLEOTIDE, which is required for the functioning of various POLYMERASES. In DNA REPLICATION, the primer is a short RNA sequence that anneals to the DNA TEMPLATE and is extended by DNA POLYMERASE. In the POLYMERASE CHAIN REACTION, the primer is a short oligonucleotide that initiates the PCR. In OLIGONUCLEOTIDE-DIRECTED MUTAGENESIS, the synthetic oligonucleotide used to introduce the mutation is a mutagenic primer that initiates DNA synthesis.
