Question

After 12 PCR cycles how many DNA strands would be available?

Answer 1

The answer would be D. hope that helped

Answer 2

Answer;

The correct answer is supposed to be 4098 DNA strands

Explanation;

-PCR or polymerase chain reactions takes  place for the purpose of duplicating the available DNA sample.

-After every PCR cycle number of double-stranded DNA segments is doubled such that after n cycle one there will be 2^n copies of DNA.

-For example, after 10 cycles one will have 1024 copies of DNA strands. Therefore, after 12 cycles of PCR one will have 2^12 DNS strands which is about 4096 copies of DNA strands.
