Answer:
DNA primers
Explanation:
PCR uses short DNA segments called as primers. These primers become paired with the template DNA strands and are being elongated by the DNA polymerase enzyme (Taq polymerase). On the other hand, in vivo DNA replication does not use the DNA primers. Primase is the enzyme that makes RNA primers with free 3' OH end which is then elongated by DNA polymerases. The RNA primers are synthesized when the primase enzyme makes a short RNA copy of the DNA template strand.
Microscopes are necessary to study cells because cells are microscopic. This means that they can’t be seen by the naked eye and using a microscope allows scientists to zoom in and see all parts of a cell.
