A) True
B) False
12) Which of the following is true regarding steroid hormones?
A) Estrogen and testosterone are examples.
B) They ultimately lead to altered gene expression in their target cells.
C) Steroid receptor proteins are within the target cells.
D) All of the above are true.
13) Cloning experiments using adult epithelial DNA and enucleated egg cells show that adult cells have all the genes necessary to form a complete organism. However, due to differential gene expression adult cells are not normally totipotent.
A) True
B) False
