When a steroid hormone and a polypeptide hormone exert similar effects on a population of target cells, then ________.

#Zoology
  1. the steroid and polypeptide hormones must use the same biochemical mechanisms
  2. the steroid and polypeptide hormones must bind to the same receptor protein
  3. the steroid hormones affect the synthesis of effector proteins, whereas polypeptide hormones activate effector proteins already present in the cell

  4. the steroid hormones affect the activity of certain proteins within the cell, whereas polypeptide hormones directly affect the processing of mRNA
