Which of the Following is a Fundamental Characteristic of the Notch

Question

Which of the following is a fundamental characteristic of the Notch pathway?
A) It directs mRNAs to antisense systems in the posterior portion of all organisms.
B) It works through direct cell -to -cell contact.
C) It provides symmetry to plant flowers.
D) It works through nuclear signals involving the lac operon.
E) It allows mRNAs to accumulate in the posterior portion of the Drosophila embryo.

Accepted Answer

The Notch pathway is a highly conserved cell signaling system that involves direct cell-to-cell contact, where the Notch receptor on one cell interacts with ligands on an adjacent cell.
