Examine the three protein monomers From the arrangement of c

Examine the three protein monomers: From the arrangement of complementary binding surfaces, which are indicated by similarly shaped protrusions and invaginations, decide which monomer would assemble into a ring, which would assemble into a chain, and which would assemble into a sheet.

Solution

When monomer A binds its complementary binding site it will form sheet because this monomer has two protrusions and two invaginations likewise, monomer B will form chain and monomer C will create a ring.
