How many cycles of PCR would it take to create 16 copies of a DNA molecule?​

Answer:

Explanation:

The number of double stranded DNA pieces is doubled in each cycle, so that after n cycles you have 2^n (2 to the n:th power) copies of DNA. For example, after 10 cycles you have 1024 copies, after 20 cycles you have about one million copies, etc.

Four (4) cycles of PCR would it take to create 16 copies of a DNA molecule. In each PCR cycle, the target DNA sequence is duplicated.

The polymerase chain reaction (PCR) is a widely used technique in molecular biology in order to amplify a specific nucleotide (DNA) sequence.

In each PCR cycle, both DNA strands are separated and the target DNA is then amplified to produce two new identical double-strand DNA molecules.

In consequence, four cycles will create 16 DNA target molecules (2⁴ = 16).
