- 1. Multiple ChoiceWhat mutation has occurred here?
T-G-A-C-C-A
T-G-A-G-C-ASubstitutionDeletionInsertionFrameshift - 2. Multiple ChoiceAre all mutations bad?YesNo
- 3. Multiple Choice
In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount ofcytosineguaninethymineuracil - 4. Multiple ChoiceAny change in the sequence of DNA is...transgenic shiftSingle GenotypeMonohybrid TraitMutation
- 5. Multiple ChoiceWhy are insertion and deletion (frameshift) mutations so harmful?They change all of the codons from the mutation on down the line, which changes the amino acid sequenceThey insert things that an organism doesn't need.They often delete things that organisms need.Insertion and deletions are not any more harmful than substitution mutations.
- 6. Multiple ChoiceWhy is the order of amino acids so important?The order of amino acids dictates what shape the protein will fold into.It is not important. The protein folding chamber will force the protein to fold into the correct shape.
- 7. Multiple ChoiceDNA molecule segment is : TTACGCAAG
The mutated DNA segment is TTACGCAAC. This is an example of ___ mutation.Base SubstitutionBase InsertionBase InversionTranslocation - 8. Multiple ChoiceDNA molecule segment is : TTACGCAAG
The mutated DNA segment is TTCGCAAG. This is an example of ___ mutation.SubstitutionDeletionInsertionInversion - 9. Multiple ChoiceDNA molecule segment is : TTACGCAAG
The mutated DNA segment is TTACGCAAC. This is an example of ___ mutation.SubstitutionInsertionInversionTranslocation - 10. Multiple ChoiceWhich RNA bases would pair with TACGAA in transcription?AUGCUUATGCTTGCATCCGCAUCC
- 11. Multiple Choicea change in one DNA triplet that may result in a new triplet that codes for a stop codon instead of an amino acid is known asmissensenonsenseframeshiftsilent
- 12. Multiple ChoiceA type of substitution in which no amino acids change is calledMissenseNonsenseSilentDeletion
- 13. Multiple ChoiceThis type of substitution codes for a stop codonMissenseNonsenseSilentDeletion
- 14. Multiple ChoiceIn a point mutation, this would have the worst effect on the function of the proteinan insertion or deletion near the end of a genean insertion or deletion at the beginning of the genean insertion at the middle of the genea base substitution
- 15. Multiple ChoiceMutations are__________HarmfulHarmful or beneficialNeutralHarmful, neutral, or beneficial
- 16. Multiple ChoiceWhich of the following can increase the rate of mutation?UV RadiationVirusestoxic chemicalsAll of the above
- 17. Multiple ChoiceA frameshift mutation would result from...a base deletion onlya base substitution onlyeither an insertion or deletion of a basea base insertion only
- 18. Multiple ChoiceA missense mutation results from...a base substiution that causes no change in amino acida base substitution that causes a change in one amino acida base change that codes for a stopa base insertion or deletion
- 19. Multiple ChoiceYOU NEED YOUR CODON CHART!
