The focal complexes that form near the leading edge of a motile cell exert traction force through their associated __________ and then typically disassemble as the cell moves forward or mature into larger, more contractile focal adhesions.
A)microtubules
B)keratin filaments
C)vinculin filaments
D)actin filaments
E)actinin filaments

Question

Quizplus · Accepted Answer

Focal complexes are structures composed of actin filaments and associated proteins that are involved in adhesion and migration of cells. These structures exert traction force through the actin filaments and then either disassemble or mature into larger focal adhesions. Microtubules, keratin filaments, vinculin filaments, and actinin filaments are not typically associated with these structures.
