The pathway for polypeptides exported from E. coli includes the following steps, which occur in what order for correct export?
1. A chaperone, SecA, binds to the polypeptide.
2. A chaperone, SecB, binds to the polypeptide.
3. ATP is hydrolyzed by Sec A.
4. SecA pushes 20 amino acids of the polypeptide into the translocation complex.

#Unit 5. Developmental Biology
Following statements are regarding to the specification
of anterior-posterior axis in drosophila.
A. The oocyte moves into the posterior region
of the egg chamber, while nurse cells fill the anterior portion. The oocyte
nucleus moves toward the terminal follicle cells and synthesizes Gurken
protein.
B.
When Gurken binds to Torpedo, the terminal follicle cells differentiate into
posterior follicle cells and synthesize a molecule that activates protein
kinase A in the egg.
C.
Bicoid mRNA binds to dynein, a “plus-directed” motor protein associated with
the nongrowing end of microtubules; dynein moves the bicoid mRNA to the
anterior end of the egg.
D.
Oskar mRNA becomes complexed to kinesin I, a “minus-directed” motor protein
that moves it toward the growing end of the microtubules at the posterior
region, where Oskar protein can bind nanos mRNA.
