DNA replication and mitosis in a cell culture

/in /by

Assume a drug slows down the processes of DNA replication and mitosis in a cell culture, but the overall length of the cell cycle for these cells remains the same. Which of the following would be true:

    • The proportion of cells in culture found in S and M phase would decrease, and the proportion found in G1 and G2 would stay the same.
    • The proportion of cells in culture found in S and M phase would stay the same, and the proportion found in G1 and G2 would decrease.
    • The proportion of cells in culture found in G1 and G2 would decrease.
    • The proportion of cells in culture found in S and M phase would increase, and the proportion found in G1 and G2 would stay the same
