Question

You recently discovered four new chemical mutagens (#1 - #4), but you do not know what type(s) of mutations these chemicals induce. You exposed E. coli to each chemical individually and observed mutant phenotypes. You then exposed this bacteria to a second known mutagen to observe if the mutations from chemicals #1 - #4 could be reversed. Your data is presented below. Mutations Induced by Mutations Reversed by Chemical EMS Acridine Orange 5-Bromouracil #1 No Yes No #2 Yes No Yes #3 Yes Yes Yes #4 No No No What type(s) of mutations are likely produced by chemical #3? A. transversions B. transitions C. frameshifts What type(s) of mutations are likely produced by chemical #4? A. transversions B. transitions C. frameshifts (SELECT ALL THAT APPLY)

Explanation / Answer

Answer

Chemical 1: Frameshift mutation

Chemical 2: Transition

Chemical 3: Frameshift mutation and transition

Chemical 4: Transversion
