Which of the following would result in a frameshift mutation?
Insertions only
Substitution only
Deletion only
Insertions and Deletions
DNA molecule segment is : TTACGCAAG
The mutated DNA segment is TTCGCAAG. This is an example of ___ mutation.
Substitution
Deletion
Insertion
Inversion
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
What mutation has occurred here?
T-G-A-C-C-A
T-G-A-G-C-A
Substitution
Deletion
Insertion
Frameshift
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.
Which mutation will cause translation to stop?
Mutations 1 and 3 only
Mutation 1 only
Mutation 2 only
Muations 1, 2, 3
