Results:

  • Amplification of DelG did not work, no product was detectable
  • PCR will be repeated at higher temperature to decrease formation of secondary structures and thereby improve binding of primers to the desired sequence

Results:

  • Amplification of DelG was not sucessful, the Re-PCR did not yield the desired product
  • forward Primer will be reused but reverse primer changed, in order to obtain a shorter amplicon and another strategy for the Gibson Assembly
