BOTANY

Detailed explanation-1: -Typically, the goal of PCR is to make enough of the target DNA region that it can be analyzed or used in some other way. For instance, DNA amplified by PCR may be sent for sequencing, visualized by gel electrophoresis, or cloned into a plasmid for further experiments.

Detailed explanation-2: -PCR makes it possible to produce millions of copies of a DNA sequence in a test tube in just a few hours, even with a very small initial amount of DNA.

Detailed explanation-3: -The number of double stranded DNA pieces is doubled in each cycle, so that after n cycles you have
