Template
Definition:
(n.) Same as Templet.
Example Sentences:
(1) These lysates are comparable to those of Escherichia coli in transcriptional and translational fidelity and efficiency in response to a given template DNA.
(2) The RNA polymerase activity was tested after the solubilization and chromatographic resolution of the three types of polymerases with exogenous template.
