Biology Final Exam Review Part 1

If you are missing or have an extra base  at the end of your mutated DNA . What type of mutation occurred?

• Frameshift deletion
• Frameshift insertion 
• Point nonsense

• nucleotides
• ribosomes
• Amino Acids

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.
