State
FtsZ and tubulin, the building block of eukaryotic microtubules, are homologous structures sharing a common evolutionary origin, both using GTP to rapidly assemble and disassemble.
Show
FtsZ forms filaments and rings resembling the structures tubulin forms in a mitotic spindle, evidence of a shared ancestor.
Watch for
This resemblance reflects shared ancestry, not a claim that division is identical in both domains.
