Now can we use DNA polymerase to extend this primer?

Examples

  • Once it is turned on, the RNA polymerase starts walking down the DNA double Helix, making messenger RNA.

  • During DNA replication, the polymerase enzyme synthesizes a new strand by adding nucleotides complementary to the existing DNA template.

  • Another useful test is the polymerase chain reaction assay, but it is not widely available, primarily because of its high cost.

Surface Forms

polymerase singular
polymerases plural

Morphology

polymerase = polymer (semi-transparent) = polymer + ase

Formed from 'polymer' + the technical enzyme-forming suffix '-ase'; the suffix is specialized vocabulary so the full meaning may not be obvious to general learners.

Etymology

Polymerase comes from Greek parts poly- 'many', mer- 'part', and the ending -ase 'enzyme', as in lactase. So a polymerase is an enzyme that joins many small parts into long chains, which is what it does when it builds DNA or RNA.
