Mutagens such as 5-bromouracil cause mutations by:
A)substituting for one of the bases normally found in DNA
B)adding an alkyl group to a nucleotide
C)removing an amino group from a nucleotide
D)causing breaks in chromosomes

Question

Quizplus · Accepted Answer

Mutagens such as 5-bromouracil are known as base analogues, as they have a chemical structure similar to the nitrogenous bases found in DNA. These mutagens can substitute for the normal base, leading to errors in replication and DNA repair that can result in mutations.
