  A.Proteins

  B.Cellular activities

  C.Functions

   D.DNA sequences

Question 3:

  A.Disintegrate

  B.May increase or decrease their level             of expression or activity

  C.Gradually decrease their level of             expression

  D.Gradually turn into protein

Question 4:

Question 5:

Which statement about genes and human disease is most accurate?

  A.Knowing the DNA sequence of all              your genes is sufficient information             to predict the occurrence of              any genetic disease.

  B.Genetic diseases are most reliably              predicted by family history rather             than DNA testing.

  C.Whereas some genetic diseases             can be predicted based on the             presence of a particular gene              sequence, other genetic diseases             are too complex to be predictable             at this time.

  D.Environmental factors have little             influence on disease occurrence.
