A)bacteria do not get cancer they can survive lethal carcinogens.
B)mutagens that affect bacterial DNA are likely to cause human mutation.
C)bacteria thrive on substances that could cause cancer in humans.
D)the same genes that cause cancer in humans can be mutated in bacteria.
E)liver enzymes alter the bacteria so they will behave like mammal cells.

Question

The Ames test is based on the principle that mutagens that cause mutations in bacterial DNA are likely to cause mutation in human DNA as well. This is because the basic mechanisms of DNA repair and replication are conserved across different species. Therefore, the Ames test is a useful tool to screen potential carcinogens and to identify chemicals that may pose a risk of cancer in humans.
