FtsZ and Tubulin: Homologous Structures
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
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.
