It should be 16, since the number of DNA molecules produced at the end of each cycle is =2^n.
Where n is the number of cycles.
So =>2^4 = 16.
Where n is the number of cycles.
So =>2^4 = 16.

I think it should be 16.

It should be 16.

If the question is DNA molecule after the completion 4th cycle then it will not b 4. It is 16.
The formulae is 2 to the power n. N is number of cycle.

The answer should be Two ds DNA molecule.

You are correct @Devanshi.

Answer is correct because in question, you can see they ask during 4th cycle not after completing 4th cycle. So the Answer would be 4.

I also agree with you @Ann.
The given answer of 4 ds DNA is wrong.
The given answer of 4 ds DNA is wrong.

1 cycle of PCR yields 2 ds DNA, then obviously 4 cycles should give 8 ds DNA.

How this possible? The question is unclear. How many DNA molecule are present before 4th cycle?
If 1 then the answer is 2 and it's right but if we start from first and go step wise then the answer is 8.
