The Polymerase Chain Reaction (PCR) is used to replicate segments of DNA. It is used to make DNA samples big enough for testing, starting from very small samples collected, for instance, from a crime scene. PCR can double the number of a particular DNA segment every two minutes. If one wants a DNA sample with copies of a particular segment, how long must the PCR process be carried out to produce them? Assume that there is just one segment in the original sample.
A) 133 minutes
B) 66 minutes
C) 23 minutes
D) minutes
