Which of the following drugs acts as an imposter of a building block necessary in the formation of DNA, thereby interfering with the normal production of DNA and resulting in cell death?

Question

Quizplus · Accepted Answer

Antimetabolites are drugs that mimic or imitate the structure of natural building blocks within the cell, such as the nucleotides used in DNA synthesis. By mimicking the structure, the antimetabolites can interfere with or block the normal metabolic processes that are required for DNA synthesis and cellular replication. As a result, the cells cannot efficiently produce new DNA, leading to cell death. Alkylating agents, antibiotic antitumor drugs, and mitotic inhibitors may also interfere with DNA synthesis or cell replication in different ways, but they do not act as direct imposters of building blocks like antimetabolites.
