Mutations

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

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.

Match the type of mutation with its definition:

• Substitution

• when one nucleotide is added into the DNA sequence

• Deletion

• when one nucleotide is switched for a different one in the DNA sequence

• Insertion

• when one nucleotide is removed from the DNA sequence
