A gene 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 sequence that makes a protein

A mutation in which only one nucleotide is altered is called a:

• Frameshift Mutation

• Deletion Mutation

• Point Mutation

• Insertion Mutation

Tags

NGSS.HS-LS3-2

Another name for a point mutation is:

• Substitution

• Frameshift

• Insertion

• Deletion

Tags

NGSS.HS-LS3-2

This type of frameshift mutation involves inserting a piece of DNA where it does not belong.

• Substitution Mutation

• Deletion Mutation

• Silent Mutation

• Insertion Mutation

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.
