You conduct an experiment by incorporating purple fluorescent dNTPs early in S phase, followed by gold fluorescent dNTPs late in S phase. At the conclusion of S-phase, you examine the nucleus of the cell using a fluorescent microscope and see that the only incorporated fluorescence is purple. Which one of the following represents the most likely interpretation of your results?

DNA synthesis was initiated in early S-phase instead of late S-phase

Explanation:

The Synthesis Phase (S phase) is the stage of DNA replication in the cell cycle. The S phase occurs between the G1 and G2 phases of the cycle and is regulated by evolutionarily conserved factors that finely control the DNA replication process
