- A DNA polymerase, an enzyme that synthesizes new DNA strands from the sample DNA.
- A primer which represents the starting sequence for the new strand of DNA to be synthesized.
- Free nucleotides in form of Deoxynucleoside triphosphates (dNTPs)
<em>The graduate student forgot to add primers which are essential as a starting point on which the synthesis of new DNA strand is based. DNA ligase is not needed for PCR, but during DNA replication.</em>

Im pretty sure that is the answer sorry if its not
Sterile powdered agar with nutrients can be mixed with water, heated and then poured into empty petri plates or ready-to-use dishes can be purchased.
