Mutations

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 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 

In order for offspring to get a genetic mutation, the mutation must occur in what type of cell?

• Cells with no nucleus.

• Any body cell after birth.

• Cells with no cell wall or cell membrane.

• Cells like eggs or sperm cells that are undergoing reproduction.

A frameshift mutation where a nucleotide base

is removed from the DNA sequence.

• Deletion Mutation

• Substitution Mutation

• Translocation

• Silent Mutation

A frameshift mutation where a nucleotide base is added

to the DNA sequence

• Insertion Mutation

• Deletion Mutation

• Substitution Mutation

• Chromosomal Mutation

Part of a chromosome is repeated

• Gene Mutation

• Point Mutation

• Deletion Mutation

• Duplication 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

A point mutation where one nucleotide base replaces an original nucleotide base

• Inversion Mutation

• Chromosomal Mutation

• Translocation

• Substitution Mutation

Identify the DELETION mutation form the following:

ATG CCA AAT

• ATG TCA AAT

• ATG CCT AAA T

• ATC CA AT

• ATG CCA AAT
