Which of the following would result in a frameshift mutation?
Insertions only
Substitution only
Deletion only
Insertions and Deletions
What mutation has occurred here?
T-G-A-C-C-A
T-G-A-G-C-A
Substitution
Deletion
Insertion
Frameshift
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
ATTTGAGCC- Original
ATTGAGCC - Mutated
The example above is an example of a
Insertion- Frameshift
Deletion- Substitution
Deletion -Frameshift
All of the above
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.
In Biology we classify mutations into what 2 types?
Chromosomal
Radioactive
Gene
Damaging
A substitution mutation that causes an amino acid change is called
missense
nonsense
silent
A substitution mutation that has no effect
on amino acids sequence
Insertion Mutation
Translocation
Silent Mutation
Deletion Mutation
A nucleotide base is inserted or deleted shifting the entire DNA sequence. Entire protein will be changed.
Substitution Mutation
Silent Mutation
Frameshift Mutation
Translocation
Mutations that involve parts of or all of
a chromosome
Replication
Deletion Mutation
Chromosomal Mutation
Transcription
Part of a chromosome is repeated
Gene Mutation
Point Mutation
Deletion Mutation
Duplication Mutation
Part of a chromosome
is deleted
Deletion Mutation-Gene
Translocation
Deletion Mutation -Chromosomal
Crossing Over
Part of a chromosome is reversed.
Inversion Mutation
Deletion Mutation
Translocation
Point Mutation
Mutations are SOMETIMES helpful to the organism.
