T-G-A-G-C-A
Substitution
Deletion
Insertion

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
ATTTGAGCC- Original
ATTGAGCC - Mutated
The example above is an example of a
Insertion- Frameshift
Deletion- Substitution
Deletion -Frameshift
All of the above
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
A change in a gene, group of genes or chromosome that results in a change in the proteins
Replication
Mutations
Translation
Transcription
A permanent change in the DNA sequence
which can affect a single gene or group of genes
Homeostasis
Somatic Cell
Chromosomal Mutation
Gene Mutation
One nucleotide base is changed so only one amino acid
is affected
Substitution Mutation
Point Mutation
Translocation
Inverse Mutation
Mutations that involve parts of or all of
a chromosome
Replication
Deletion Mutation
Chromosomal Mutation
Transcription
Part of a chromosome is reversed.
Inversion Mutation
Deletion Mutation
Translocation
Point Mutation
Failure of homologous chromosomes
to separate during meiosis.
Results in gametes with either one extra or one missing chromosome.
Translocation
Nondisjunction
Replication
Transcription
