Answer to Question 1

ANS: B
Taking a family history is a useful place to begin when considering a genetic connection prior to the onset of testing. The best way to identify whether there is a mutation in a family where a he-reditary disease is suspected is to test the person who displays the most evidence of being a mu-tation carrier. This would take precedent over assessing vital signs, current medications, and past medical history.

Answer to Question 2

ANS: C
A large number of agents are known to cause mutations. These mutations are attributed to known environmental causes. DNA replication is very accurate, thus, mutations do not occur on a regular basis. Mutagens are the factors that cause mutations. Spontaneous mutations occur naturally dur-ing DNA replication.
