What mutation occurred?deletioninsertionsilenttransverse - 7. Multiple ChoiceWhich organelle is DNA usually found in?cell membranevacuolechloroplastnucleus
- 8. Multiple Choice
Which of the following would result in a frameshift mutation?
Insertions only
Substitution only
Deletion only
Insertions and Deletions
- 9. Multiple Choice
A mutation is defined as:
A change in the cell's structure
Anything that changes in an embryo
Any change in the physical features of a human
A change in the DNA sequence
- 10. Multiple Choice
Why 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 sequence
They 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.
