The Major Shape-Determining Factor in Bacteria is the Protein

Question

The major shape-determining factor in Bacteria is the protein
A) FtsZ.
B) crescentin.
C) MreB.
D) MinD.

Accepted Answer

MreB is a cytoskeletal protein that forms helical filaments underneath the cell membrane and plays a major role in determining the rod-like shape of many bacterial species.

Option A, FtsZ, is involved in cytokinesis and forms a ring at the site of cell division.

Option B, crescentin, is a protein that forms a curved filament and is responsible for the curved shape of Caulobacter crescentus.

Option D, MinD, is involved in the regulation of the placement of the FtsZ ring during cytokinesis in many bacterial species.
