7. j. frameshift mutation: mutation that shifts the “reading frame” of the genetic message by inserting or deleting a nucleotide
8. a. mutagen: chemical or physical agents in the environment that interact with DNA and may cause a mutation
9. c. mutation: change in the genetic material of a cell
10. i. point mutation: gene mutation in which a single base pair in DNA has been changed
11. d. polyploidy: condition in which an organism has extra sets of chromosomes
