Induced Mutations

Select which examples are induced mutations. A) Nitrous acid causes the deamination of cytosine to uracil B) Ionizing radiation causes chromosomal fragmentation.C)Error in DNA replication cause the formation of point mutations.D) Transposition causes the formation of deletions.

Select which example are induced mutations.a. nitrous acid causes the deamination of adenine to hypoxanthine.b. transposition causes the formation of deletions.c. errors in DNA replication cause the formation of point mutations.d. ionizing radiation causes chromosomal fragmentation

Which of the following might result in a frameshift mutation?A. Nitrous acidB. 5-bromouracilC. Benzo(a)pyrene

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 Mutations Induced ByMutations Reversed ByChemicalEMSAcridine Orange5-Bromouracil#1NoYesNo#2YesNoYes#3YesYesYes#4NoNoNoWhat 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
