Quiz - Mutation

Which of the following would result in a frameshift mutation?

• Insertions only
• Substitution only
• Deletion only
• Insertions and Deletions

Where do mutations occur?

• DNA and RNA
• DNA 
• RNA
• mRNA and tRNA

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.

A type of substitution in which one amino acid changes is called 

• Nonsense
• Missense
• Silent
• all of the above

DNA molecule segment is : TTACGCAAG

• Inversion

This type of substitution codes for a stop codon

• Missense
• Nonsense
• Silent
• Deletion

A type of substitution in which no  amino acids change is called 

• Missense
• Nonsense
• Silent
• Deletion

chromosomal mutations cause a segment of the chromosome to repeat itself during replication.

• inversion

• duplication

• translocation

• deletion

Point mutation involves

• deletion

• insertion
