What mutation occurred?
What type of gene mutation has occurred here? Normal-
AGA-TTC-ATA-GCG
Mutant-
AGA-TTC-AAT-AGC-G
deletion frameshift
insertion frameshift
substitution
nonsense
Why are insertion and deletion 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.
What do gene mutations change?
DNA
RNA
Proteins
Lipids
A mutation in which only one nucleotide is altered is called a:
Frameshift Mutation
Deletion Mutation
Point Mutation
Insertion Mutation
The mutated DNA segment is TTCGCAAG. This is an example of ___ mutation.
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
ATG CCA AAT
ATG CCA AAT
What type of mutation is shown in the diagram?
Point mutation - missense
Frameshift Mutation - deletion
Frameshift Mutation - addition
Point mutation - nonsense
