Assume That You Discovered a New Chemical Mutagen That Modifies

Multiple Choice

Assume that you discovered a new chemical mutagen that modifies guanine so that is mispairs with adenine when adenine is in the template DNA strand during DNA replication.However, this mispairing is limited to when the modified guanine is being added to the newly replicating DNA strand.When the modified guanine is in the template DNA strand it always pairs normally with cytosine being added to the growing newly-synthesized strand.What type of mutation would you predict would be caused by the new chemical mutagen?

A) A-to-G base substitutions
B) A-to-C base substitutions
C) A-to-T base substitutions
D) A-to-G and A-to-C base substitutions
E) G-to-T base substitutions
