Strikingly different signaling systems can operate in similar ways. For example, ethylene gas released by ripening fruits diffuses through the air from plant to plant and functions as a "fruit ripening" signal; oxytocin, a peptide hormone secreted into the blood of female mammals, activates milk excretion from the mammary glands. Both signaling molecules initiate an intracellular signal- transduction cascade. Which of the following best describes a mechanism common to BOTH tpes of signaling systems?

Please choose one of these choices.
Strikingly different signaling systems can operate in similar ways. For example,
ethylene gas released by ripening fruits diffuses through the air from plant to
plant and functions as a "fruit ripening" signal; oxytocin, a peptide hormone
secreted into the blood of female mammals, activates milk excretion from the
mammary glands. Both signaling molecules initiate an intracellular signal-
transduction cascade. Which of the following best describes a mechanism
common to BOTH tpes of signaling systems? *
The signaling molecules bind to specific receptor proteins on the cellular surfaces of
their "targets."
A carrier protein binds to the signaling molecules and transports them to their target
cells.
Signaling molecules are taken up into the target cells and bind to specific DNA
sequences.
Signaling molecules bind to second messenger molecules in the nucleus to alter gene
expression.
