Question

which is true concerning microfilaments? select all that apply a made of actin b two chains twisted around each other. c allows movement of certain cells d involved in some cell to cell junctions

Explanation:

Microfilaments are composed of actin monomers that polymerize to form two - stranded helical structures. They play a role in cell movement (such as in amoeboid movement) and are also involved in some cell - to - cell junctions like adherens junctions.

Answer:

A. made of actin, B. two chains twisted around each other, C. allows movement of certain cells, D. involved in some cell to cell junctions
