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

Question

Quizplus · Accepted Answer

The Notch pathway is based on direct cell to cell contact, making option B the correct choice. Option A is incorrect because the Notch pathway does not involve the lac operon. Option C is also incorrect because the Notch pathway does not specifically direct mRNAs to accumulate in the posterior portion of the Drosophila embryo. Option D is not a characteristic of the Notch pathway at all, making it incorrect. Option E is incorrect because the Notch pathway does not provide symmetry to plant flowers.
