Answer:
One strand of all the isolated DNA double helices would have C-14 labeled thymidine.
Explanation:
DNA replication is a semiconservative process which means that each newly formed DNA double helix contains one parental strand and one newly formed strand.
Since the medium has thymidine labeled with C-14, all the newly formed strands formed during DNA replication would have radio-labeled thymidine.
Therefore, by the end of 20 minutes, one out of two strands on each double helix would have labeled thymidine nucleotides.
