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

• Missense
• Nonsense
• Silent
• Deletion

If one amino acid is substituted for another, this is referred to as a

• insertion mutation

• point mutation

• nonsense mutation

• nondisjunction mutation

What is a codon?

• It is a three letter section of bases that are read by ribosomes to stamp amino acids into a protein
• They are the codes on the DNA (hence "code-on"
• It is a type of mutation that occurs when there has been a substitution, deletion or insertion.
• It is a made up word for this quiz. Nice try, Wampler.

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.
