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

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
