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.

This diagram can be used to specify amino acid sequences in proteins (polypeptides). Which sequence of the genetic code would produce a polypeptide with the amino acid sequence Ala-Arg-Pro? 

• GCAAGACCU
• GACCUGCUC
• GCCAGUCCG
• ACGGCGUCC

• TCT
• TCC
• GCA

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
