Answer:
The correct answer would be -
Blank 1) dimerize,
Blank 2) signaling molecule, and option a) true.
Explanation:
Dimerization takes place after the signaling molecules attach to the receptor. Dimerize of antibody takes place when the antibody bind to the two parts of the receptors.
Even in the absence of a signaling molecule, signal transduction occurs. It could be possible due to mimicking the interaction and activate the receptor.
Thus, the correct answer is-
Blank 1) dimerize,
Blank 2) signaling molecule, and option a) true.
