Question

select the correct answer.
many types of cancer cells divide rapidly due to defects in the genes that control cell division. which phase of the cell cycle is the target of many chemotherapy age

Explanation:

Chemotherapy agents often target the S phase (synthesis phase) of the cell cycle. In this phase, DNA replication occurs. Many chemotherapy drugs work by interfering with DNA synthesis or replication. For example, some drugs act as nucleoside analogs and get incorporated into the DNA strand during replication, causing errors and ultimately cell death. Since cancer cells divide rapidly (and thus go through the cell cycle, including the S phase, frequently), targeting the S phase can effectively disrupt their growth.

Answer:

S phase.
