FtsZ is a bacterial cytoskeletal protein that forms a contractile ring involved in binary fission. Its function is analogous to ________.
A) the cleavage furrow of eukaryotic animal cells
B) the cell plate of eukaryotic plant cells
C) the mitotic spindle of eukaryotic cells
D) the microtubule-organizing center of eukaryotic cells

Question

Quizplus · Accepted Answer

FtsZ forms a ring-like structure, the Z-ring, at the site of cell division in bacterial cells. This ring contracts and eventually splits the cell in two, similar to the process of cytokinesis in eukaryotic animal cells, which is mediated by the formation of a cleavage furrow.
