Emilee Chen · Answer 1

C. coccoid-shaped.

Explanation:

MreB protein serves as function as actin proteins do in the eukaryotic cells. MreB protein is involved in maintaining the cell shape. It is observed in many rod-shaped bacteria and archaea such as Bacillus subtilis. MreB polymerizes to form a spiral around the inside periphery of the cell and maintain the elongated shape of the cell. A bacterium that is not able to produce functional MreB protein cannot maintain the rod shape of its cell and is coccoid-shaped.
