During Vulval induction in C. elegans, the anchor cell secretes, a paracrine factor which receives by VPCs and become vulva. If the anchor cell is destroyed, the VPCs will not form a vulva. This is the example of:

With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 

You do each PCR reaction on chromosome 15 and load each one into a separate well of an agarose gel, and then run the gel.

Following statements are regarding to the formins which involve in filament assembly.

A. All formin family members have two adjacent domains in common, the so called FH1 and FH2 domains (formin-homology domains 1 and 2).

B. Two FH2 domains from two individual formin monomers associate to form a doughnut-shaped complex can form a dimer and nucleate filament assembly.

C. The FH1 domain of formin is rich in proline residues, which serve as sites for the binding of several profilin molecules.

D. The FH2 domain behaves as a landing site for profilin–ATP–G-actin to increase the local concentration of these complexes.

E. Formins are activated by membrane bound Rho-GTP, a Ras-related small GTPase.

Which of the following combination is correct?
