Claudins and occudins are proteins that form
A
tight junctions
B
adhering junctions
C
gap junctions
D
None of the above
Explanation: 

Detailed explanation-1: -Occludin-and claudin-based tight junctions are components of the BTB, which is located apical to preleptotene spermatocytes and basal to pachytene spermatocytes in the seminiferous epithelium .

Detailed explanation-2: -Claudins are a family of proteins which, along with occludin, are the most important components of the tight junctions (zonulae occludentes). Tight junctions establish the paracellular barrier that controls the flow of molecules in the intercellular space between the cells of an epithelium.

Detailed explanation-3: -The tight junction protein, occludin, regulates the directional migration of epithelial cells.
