Which of the following statements best describes the amplification of DNA in each PCR cycle?Group of answer choicesThe number of double stranded DNA molecules produced that contain the target sequence DOUBLES with each PCR cycleThe number of double stranded DNA molecules produced that contain the target sequence INCREASES BY 2 molecules with each PCR cycleThe number of double stranded DNA molecules produced that contain the target sequence INCREASES BY 1 molecule with each PCR cycleThe number of double stranded DNA molecules produced that contain the target sequence REMAINS CONSTANT with each PCR cycle

Organize the following steps of a PCR cycle in the correct sequence.The mixture is cooled to allow the binding of primers to the end of target DNA sequences.Free nucleotides are added in the 5’ to 3’ direction by the Taq DNA polymerase.The reaction mixture is heated to separate the double-stranded DNA.Group of answer choices1, 2, 31, 3, 22, 1, 32, 3, 13, 1, 23, 2, 1
