Question

1) 106 minutes 2) 53 minutes 3) 18 minutes I need a full demonstration to give full credits 1) 106 minutes 2) 53 minutes 3) 18 minutes 4) minutes 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 ten to the power of sixteen 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.

Explanation / Answer

let number of PCR process be n

2^(number of PCR process) = At /Ao

2^n = 10^16

taking log

2*log(n) = 16

log(n) = 8

n = 10^8
