1. QuestionPolymerase chain reaction (PCR) is a DNA manipulation technique used to: Cut DNA molecules at specific sequences of nucleotides Separate DNA molecules according to size Join molecules of DNA together Copy specific regions of DNA2. QuestionWhat occurs in the first step of PCR? DNA strands are separated by heating them Primers bind to target DNA strands Taq DNA polymerase builds a new DNA molecule using the target strand as a template3. QuestionWhat occurs in the second step of PCR? DNA strands are separated by heating them Primers bind to target DNA strands Taq DNA polymerase builds a new DNA molecule using the target strand as a template4. QuestionWhat occurs in the final step of PCR? DNA strands are separated by heating them Primers bind to target DNA strands Taq DNA polymerase builds a new DNA molecule using the target strand as a template5. QuestionWhy are the two strands of nucleotides in a DNA molcule required to be separated during PCR?6. QuestionReferring to the image below, which primer will bind to the sequence of nucleotides? Primer 1 Primer 2 Neither primer will bind7. QuestionHow does Taq DNA polymerase extend a new strand of nucleotides? By adding nucleotides that are identical to the original strand By adding nucleotides that are complementary to the original strand By joining primers together

The process that makes an exact copy of a cell’s DNA is calledA. conservationB. preservationC. replicationD. synthesis
