A substance that alters DNA and can cause genetic changes is called what?

Explanation:
Mutagens are substances that alter DNA and can cause genetic changes. DNA mutations are changes in the sequence of nucleotides, and mutagens increase the rate of these changes by damaging DNA or interfering with replication and repair. This direct link to DNA alteration helps explain why some mutagens are associated with cancer, but the term specifically refers to DNA-level changes rather than cancer risk alone. Teratogens cause birth defects during development, not necessarily through direct DNA alteration in all cases. Carcinogens promote cancer and may do so in part by causing mutations, but the word mutagen centers on inducing genetic changes. Epidemiology is the study of how diseases spread in populations, not an agent that changes DNA.
