Notch and Delta are both transmembrane proteins involved in cell communication in the developing nervous system of vertebrate animals. What makes Notch different from Delta?

Question

Quizplus · Accepted Answer

Notch is a receptor protein that binds to the Delta protein, which acts as a signaling molecule. Notch signaling can alter the fate of cells, and it requires the presence of Delta at a lower concentration than Notch for the signaling to occur. Therefore, option A is correct. Option B is incorrect because Notch is not a signaling molecule, and Delta is not a receptor. Option C is incorrect because it is the opposite of the correct statement. Option D is incorrect because only option A is correct.
