Question

What is the effect of attacking the cells in the S period of reproduction by interfering with purine or pyrimidine synthesis?

1) It will prevent DNA replication
2) It will increase the rate of DNA replication
3) It will have no effect on DNA replication
4) It will cause mutations in the DNA

Answer 1

Attacking the cells in the S period of reproduction by interfering with purine or pyrimidine synthesis will prevent DNA replication.

Step-by-step explanation:

The effect of attacking the cells in the S period of reproduction by interfering with purine or pyrimidine synthesis is that it will prevent DNA replication. During the S phase of the cell cycle, DNA replication occurs, and both purine and pyrimidine bases are necessary for the synthesis of new DNA strands. If the synthesis of purines or pyrimidines is disrupted, the cell will not have the necessary building blocks to replicate its DNA.
