The effect of the poison is to make the ligase enzyme stops working.
We can arrive at this answer because:
- The ligase enzyme has the function of joining the old strand of DNA with the new strand that was produced by the DNA polymerase.
- In the diagram shown below, we can see that in part of the DNA molecule, the ligase managed to join the two strands of DNA, but part of these strands still does not join the new strand.
We can conclude that the poison acted at this point in DNA replication, preventing the ligase from joining the two strands and causing the new strand to fail to adhere and was lost during the process.
The question above is incomplete, but its full version can be seen in the figure below.
