#Part-A Aptitude & General Biotechnology
  1. The polymerase chain reaction (PCR) is a cell-free method of DNA amplification.
  2. PCR is usually used to amplify a specific DNA sequence of interest using oligonucleotide primers that bind to closely flanking sequences.
  3. PCR is superior to cell-based DNA cloning for two major reasons: it is much quicker and it allows much greater DNA amplification.
  4. PCR requires the use of a heat-stable DNA polymerase to make copies of the template DNA.
