Under pharmacist supervision, pharmacy technicians: 1  supply medicines to patients, whether on prescription or over the counter. 2  assemble medicines for prescriptions.
A primer is a short nucleic acid sequence that provides a starting point for DNA synthesis. In living organisms, primers are short strands of RNA. A primer must be synthesized by an enzyme called primase, which is a type of RNA polymerase, before DNA replication can occur.
Since PCR is, basically, replication of DNA in a test-tube, all the usual ingredients needed for DNA replication are required: A template. Primers. DNA polymerase. dNTPs (deoxynucleoside triphosphates used to make DNA). The template is the DNA that contains the target sequence you want to amplify. The primers are synthetic DNA molecules whose sequence matches a region flanking the target you are trying to amplify.
