Every time you replicate DNA you get 2 new DNA and 1 strand of each DNA is composed of the parent strand. So after 3 rounds of replication....
1 --> 2 ---> 4 ---> 8
Out of these 8, 2 of them contain the parent strands. So 2/8 = 1/4 = 25%

Thus the answer is the third option, eight (8).

Answer:

eight

Explanation:

In the first stage of DNA replication each DNA molecule replicates into two daughter DNA. In the second stage of DNA replication each of the two daughter DNA molecule replicates into two daughter DNA, thus forming a total of four DNA molecules. In the third stage of DNA replication each of the four daughter DNA molecule replicates into two daughter DNA, thus forming a total of eight DNA molecules.
