The PCR reaction mixture does not include: Group of answer choices DNA containing the sequence to be amplified. DNA ligase. all four deoxynucleoside triphosphates. oligonucleotide primer (s). heat-stable DNA polymerase.

Answer: DNA ligase.

Explanation:

Polymerase chain reaction is a technique used in molecular biology by scientists to make several copies of a DNA sample which enable them to take a smaller portions of it and expand it for more detailed study.

PCR mixture is premixed and contain thermostable DNA polymerase, oligonucleotides primer, four deoxynucleodide triphosphates, Magnesium chlorides, a propietary buffer.
