Read the given paragraph and select the option that correctly fills the blanks in it. Hormones produce their effect on target tissue by binding to specific A called hormone receptors located in the target tissues only water soluble hormones usually need B receptor that generate C messenger for regulating through cell membrane and bind to E receptors, mostly nuclear receptors. The hormone receptor complex enter the nucleus and moslty regulate gene expression or chromosome function by interaction of hormone receptor complex with the genone.
