Mutations Set 3

Insertion and deletion mutations are both types of ​ (a)  

• frameshift mutations
• silent mutations
• substitution mutations

All the different types of cells in your body have ​ (a)   DNA

• the same
• different

When cells choose which genes of the DNA are turned "on" or "off," this is called

• Gene differentiation

• Gene regulation

• Gene deletion

• Gene insertion

Match the type of mutation with its definition:

• Deletion

• when one nucleotide is removed from the DNA sequence

• Substitution

• when one nucleotide is added into the DNA sequence

• Insertion

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