You have a small gene that you wish replicated by PCR. You add radioactively labeled nucleotides to the PCR machine. After 3 replication cycles, how many double- stranded DNA molecules do you have?

Question

Quizplus · Accepted Answer

After 3 replication cycles of PCR, the number of double-stranded DNA molecules would be 8. PCR doubles the amount of DNA with each cycle, so after 3 cycles, it would be 2^3 = 8.
