Solution

PCR or polymerase chain reaction:

  1. PCR is a laboratory method used to make many copies of a specific piece of DNA from a sample that contains very tiny amounts of that DNA.
  2. It allows the pieces of DNA to be amplified so they can be detected.

Role of the thermocycler in PCR:

  1. It is the most important technology for scientists who want to make use of polymerase chain reaction (PCR).
  2. Thermocycler tightly controls the fluctuation in the temperature needed for annealing, denaturation, and extension.
  3. It also regulates the number of cycles.
  4. The thermocyclers which are used nowadays are fully programmable and enable rapid cooling and heating and hence the tighter control of the PCR.
