True FalseWhich of the following is/are true regarding a PCR reaction performed to amplify a DNA plasmid? There may be more than one correct answer; select all that apply. Two primers are needed to facilitate double stranded DNA extension. Denaturation, when the primers bind to the DNA template, is performed at the highest temperature. Extension is the step when the polymerase catalyzes nucleotide incorporation during polymerization. ATP, UTP, GTP, and CTP are all required for polymerization.
