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.

Why does DNA replication have to occur?

• So that it can fix any mistakes the cell made during division
• So that the cell can get grow in size
• So that each new cell will have a full set of chromosomes after mitosis
• So that each cell has a back-up copy of its DNA

A type of point mutation (substitution) in which one amino acid changes is called 

• Nonsense
• Missense
• Silent
• all of the above
